By the numbers

How often combat leaves lasting marks, and how many veterans want help.

PTSD by era

29 in 100Iraq and Afghanistan (OIF/OEF) veterans will have PTSD at some point in their lives. About 15 in 100 had it in the past year.
21 in 100Gulf War (Desert Storm) veterans will have PTSD at some point in their lives.
10 in 100Vietnam War veterans will have PTSD at some point in their lives.

Coming home

57%of Iraq and Afghanistan combat veterans in VA care said they had trouble controlling anger since coming home.
35%said they had driven dangerously since deployment.
96%said they were interested in services to help with readjusting.

Decades later

~271,000Vietnam theater veterans still had full or partial war-zone PTSD about 40 years after the war.
2×More than twice as many Vietnam veterans saw their PTSD symptoms get worse over the decades as saw them get better.
2×+Vietnam-era twin veterans with PTSD were more than twice as likely to develop heart disease over 13 years as their twins without PTSD.

Why combat stays with you

The survival brain, normal reactions, and why some don’t fade. Tap any card.

Combat asks the brain and body to stay ready for danger for days, months or years. That readiness kept you and your team alive. After you come home, the alarm system does not always get the message that the mission is over.

🛡️ Normal reactions, not weaknessStrong reactions after combat are expected.
Read more

The military calls reactions to combat “combat and operational stress reactions”. They are seen as a normal response, and having them does not mean you have a mental health disorder.

Common reactions after trauma

  • Being easily startled or always on guard
  • Feeling numb, detached or irritable
  • Intrusive memories or dreams
  • Pulling away from people
  • Trouble sleeping or concentrating
📉 For most, it easesReactions usually fade bit by bit.
Read more

VA says reactions after trauma gradually decrease over time for most people. Recovery is a process, not a switch. You may never forget what happened, and that is not the goal.

🔒 When the alarm gets stuckSome reactions last, or come back.
Read more

With PTSD, survival mode can stay switched on long after the danger is gone. The risk is higher after intense or long-lasting trauma, combat or being injured. Support from others after trauma helps protect against it.

The “Veterans: PTSD & combat stress” guide explains PTSD signs and triggers in depth. This guide looks at what living with combat’s after-effects is like, day to day.
🔁 Long and repeated deploymentsStress can pile up.
Read more

Some trauma is not one bad day. When danger goes on for a long time or happens again and again, people can carry extra struggles, like trouble managing strong feelings, feeling distant from others and trouble trusting people.

If your reactions feel deeper than you expected, it may be because you carried a lot, for a long time. That makes sense. It is not a flaw in you.

Combat skills that don’t switch off at home

What kept you alive there can cause friction here. Tap any card.

Many reactions after combat are skills that were trained and practiced until they became automatic. They were right for the war zone. At home, the same skills can look like anger, control or coldness to the people around you.

In a large Army study, soldiers back from Iraq who had training on how combat skills shift at home reported fewer PTSD symptoms if they had seen heavy combat. The effects were modest, but it shows that understanding these skills can help.

👀 Scanning for threatsThere: tactical awareness. Here: never relaxing.
Read more

Watching every doorway, hand and car kept you alive. At home, it can make it hard to relax at all, and it wears the body out over time.

Home version: check once, on purpose, then tell yourself “Checked. I can stand down.”
🎛️ Taking controlThere: command and order. Here: rules and arguments.
Read more

VA explains that trauma can leave people feeling they must control their surroundings and that others can’t be trusted. At home that can turn into strict rules, checking up on people or snapping about safety.

Home version: agree on a few safety rules together, and let the rest go.
⚡ Reacting fastThere: split-second action. Here: a short fuse.
Read more

When the body stays in survival mode, everyday stress can feel like a threat, and anger comes fast. More than half of combat veterans in one VA study said they had trouble controlling anger since coming home.

Home version: take a time-out and walk away to cool off, then come back to talk. The “Veterans: everyday coping” guide has a full anger cool-down plan.
🚗 Driving to surviveThere: speed and evasion. Here: risky driving.
Read more

About a third of Iraq and Afghanistan combat veterans in one VA study said they had driven dangerously since deployment. Driving fast, straddling lanes or tensing at debris can all be habits from the road over there.

Home version: plan routes, leave extra time, and raise driving with your provider if it stays hard.
🧊 Shutting feelings downThere: staying calm under fire. Here: seeming cold.
Read more

Pushing feelings aside helped you do the job. Back home, the same switch can turn off love and joy too, and loved ones may feel cut off from you.

Home version: name one feeling out loud each day, even a small one. See “Numb, detached, far away” below.
🤐 Trusting only your teamThere: your unit. Here: feeling no one gets it.
Read more

In a unit, you trusted people with your life. At home it can feel like nobody else understands. Pulling away from others is a common reaction after trauma, but it tends to make things harder.

Home version: let one or two people in, a little at a time. See “Trust, fear & letting people in” below.

Never quite feeling safe at home

Night watch, checking and the tiredness of always being on guard.

Home is supposed to be the place where you can let your guard down. For many combat veterans, it doesn’t feel that way. You might walk the house at night, check the locks again, or sit where you can see the door, even in your own living room.

🌙 The night watchWhen the house goes quiet, the alarm gets louder.
Read more

Night can feel like the most dangerous time, so the body stays alert. Lying awake listening for sounds, getting up to check, or waking at every noise all make sleep harder, and poor sleep then makes everything else harder.

Small steps that can help

  • Do one planned lock-up check before bed, then stop
  • If you can’t sleep, get up and do something soothing, then try again
  • Keep a regular bedtime and wake time
  • Skip alcohol, caffeine and heavy exercise close to bedtime
🔁 Checking that never feels like enoughRelief that lasts a minute.
Read more

Checking and avoiding can bring quick relief. But the more we avoid what is safe-but-scary, the bigger the fear can grow, and avoidance is one of the main things that keeps PTSD going.

Being careful is wise. The aim is only to stop the checking that has taken over your life, not to stop caring about safety.
🔋 Why you feel so tiredBeing on duty around the clock drains you.
Read more

Staying on guard all the time can lead to exhaustion, sleep problems, eating changes and stomach trouble. Needing constant reassurance can also wear out the people who love you.

🧭 Making home a base, not a postSmall changes that tell your brain it can rest.
Read more
  • Agree with family on a few simple safety habits, so you are not the only one on watch
  • Choose one room or chair where you practice letting your guard down
  • Cut back on caffeine and alcohol, which can feed anxiety
  • Try grounding, slow breathing or counting when you notice yourself scanning
  • When you feel the urge to check again, name three things that show you are safe right now
The “Veterans: everyday coping” guide has a full section, “Living with an alert brain at home”, with ideas for a home agreement.
🔐 Weapons and safety at homeSafe storage protects everyone, including you.
Read more

VA’s suicide prevention report lists unsecured firearms at home among the common risk factors in veteran suicides. Keeping firearms securely stored, especially during hard times, is one way to keep yourself and your family safer.

If you are having thoughts of hurting yourself or someone else, dial 988 then press 1 for the Veterans Crisis Line, or text 838255. If a life is in danger, call 911.

Flashbacks, nightmares & memories that intrude

What to do in the moment, after a nightmare, and how to explain it to family.

Memories of combat can push in without warning: a picture in your head, a sudden feeling of being back there, or a dream that replays it. They can be frightening, but they are memories. They cannot hurt you, even when they feel very real.

During a flashback

  1. Keep your eyes open. Look around and notice where you are.
  2. Say it to yourself: where you are, the date, and that you are safe now.
  3. Feel your feet on the floor or hold something solid. Breathe out slowly.
  4. Call or sit with someone you trust.
  5. Later, tell your counselor or doctor about it.
🌙 After a nightmareYour body reacted to a dream, not to danger.
Read more

VA suggests reminding yourself that the panic comes from having the dream, not from danger in the room right now. Getting up, turning on a light and doing something calm can help your body catch up.

Talk with your provider about nightmares. There are therapies made just for them, described in the “Veterans: PTSD & combat stress” guide.
💭 Memories that pop up in the dayNotice them, name them, let them pass.
Read more

Unwanted memories are just that: memories. Pushing them away hard often makes them come back stronger. Naming them, “There’s that memory again”, and turning back to what you were doing can take some of their power.

🗣️ Explaining it to your familyHelp them know what they are seeing.
Read more

Families may read trauma-driven behavior as rejection if they don’t know where it comes from. A short explanation on a calm day can help them respond with care.

You could tell them

  • “If I go quiet and stare, I might be somewhere else for a minute.”
  • “Say my name and where we are, calmly. Don’t grab me.”
  • “After a bad night, I may need a slow morning. It isn’t about you.”
📈 When they keep comingFrequent memories are a sign to get support.
Read more

If memories, flashbacks or nightmares get in the way of your relationships, work or sleep, it is time to talk with a counselor or doctor. Trauma-focused therapy is designed to make these memories less powerful.

Numb, detached, far away

When feelings shut down, and small ways to let them back in.

Numbness and feeling detached from others are common reactions after trauma. It can feel like watching your life through glass: present, but not really there. It is a protective response, and with support, feelings can return.

🪟 What it can feel likeGoing through the motions.
Read more
  • Doing risky things just to feel something
  • Feeling flat at happy events, like a birthday or a wedding
  • Feeling like a stranger in your own family
  • Loved ones saying you seem distant
  • Not caring about things you used to love
🎣 Do it before you feel itPleasure often comes back after you start.
Read more

VA suggests keeping up activities you enjoy or used to enjoy, even if the enjoyment isn’t there yet. Pleasure may return once you are doing them again.

Ideas

  • A short walk with your partner or a friend
  • Cooking a meal you used to like
  • Fixing or building something with your hands
  • Twenty minutes of a hobby you dropped
💌 Show care in small waysActions can carry love when words feel stuck.
Read more

Even when it is hard to feel close, small gestures like writing a card or calling someone show loved ones you care.

Tell your family it is numbness, not a lack of love. That one sentence can ease a lot of hurt.
🩺 When numbness lastsIt may be a sign of PTSD or depression.
Read more

Numbness that lasts a long time can be part of PTSD or depression. Talking with a provider can help, and trauma-focused therapy can help feelings come back.

Trust, fear & letting people in

Why trust gets hard after combat, and how to rebuild it step by step.

Combat can teach that the world is dangerous and people can turn on you. Trouble trusting others is common after long or repeated trauma. Letting people close can feel risky, and being vulnerable can feel like dropping your guard in hostile ground.

🪜 Trust is built in small stepsYou don’t have to trust everyone, all at once.
Read more

VA suggests choosing your support people carefully, and not being afraid to ask them clearly for what you need. Start with one person who has shown they are steady.

A trust ladder

  • Share a small, everyday worry and see how they respond
  • Ask for one practical favor
  • Tell them about a hard day, without details of combat
  • Let them know one thing that helps you when you are triggered
😨 Fear you don’t talk aboutFear of losing control, or of what you might feel.
Read more

Many veterans fear that if they let feelings out, they won’t be able to stop, or that people will see them differently. Hopelessness, fear, guilt and shame are all common reactions after trauma. Saying them out loud to the right person often makes them smaller, not bigger.

🔧 Repairing after a hard momentIt is never too late to go back and talk.
Read more

If you have hurt family or friends during a strong reaction, VA suggests talking with them about what happened and how you are coping. A simple repair can rebuild trust on both sides.

You could say

  • “I snapped last night. That was my alarm, not you. I’m sorry.”
  • “I’m working on this. Can we try again?”
🧱 Isolation feels safer, but isn’tPulling away makes recovery harder.
Read more

Withdrawing from others is a common reaction after trauma. VA advises making the effort to be with others rather than isolating. People who feel more socially connected tend to report better wellbeing.

If what you carry is about something you did, saw or couldn’t stop, the Moral injury and Survivor’s guilt guides may speak to it. If sexual trauma is part of your story, see the Military sexual trauma (MST) guide.

The long haul: body, health & the years ahead

How combat stress can show up in the body, and why it is never too late.

For some veterans, combat stress fades. For others it lasts for decades, or comes and goes. In a national study about 40 years after the Vietnam War, an important minority of veterans still had symptoms, and more were getting worse than better.

❤️ Stress and the heartLong-term stress can affect your body.
Read more

In an NIH-funded study of Vietnam-era twin veterans, those with PTSD were more than twice as likely to develop heart disease over 13 years as their twins without it. Researchers think repeated stress reactions may strain the heart.

Regular check-ups matter. Tell your primary care provider about your stress, sleep and mood, not just your body.
🌙 Sleep, pain and drinkingThey often travel with combat stress.
Read more

Poor sleep, headaches, stomach trouble and using more alcohol, drugs or tobacco are common after trauma. Each one can make the others worse.

See “Sleep, pain & your body after service” and “Alcohol & substance use after service” for practical help.
🧓 Getting olderRetirement, loss and quiet time can stir things up.
Read more

VA notes that PTSD symptoms can rise and fall over a lifetime. Retirement, health problems and losing loved ones can make them more noticeable later in life.

The “When PTSD shows up years later” guide goes deeper into this.
🌱 Growth is possible tooMany veterans find strength after trauma.
Read more

In a national study, about half of all U.S. veterans, and 72% of those who screened positive for PTSD, reported at least moderate growth after trauma. Social connection, faith and a sense of purpose were linked with more growth.

Growth doesn’t erase the pain. It can grow alongside it.

How family, friends & community help

What loved ones can do, and why other veterans matter so much.

Support from other people is one of the strongest protections after trauma. You don’t have to talk about combat to get it. Being around people who care, and doing things together, helps the body learn it is safe.

🏡 For family and partnersPatience, planning and looking after yourself.
Read more
  • Make a plan together for flare-ups or crises
  • Keep doing things together, with smaller groups or shorter outings
  • Look after your own needs, and think about your own counseling
  • Set regular times to talk, and come back to hard topics if the timing is off

Peer support groups can help you feel less alone, pick up tips and practice asking for help. Many VA facilities have Peer Specialists: veterans with their own recovery experience. Peer groups are not a replacement for treatment.

The Vet Center Call Center (877-927-8387) is free, confidential and open 24/7, and its team includes combat veterans.

🏘️ Wider communityBelonging beyond the veteran world.
Read more

A study of veterans found that those who felt more socially connected had better quality of life and less distress. The authors suggest connections with both veteran groups and other social groups can help.
