The Combat Veteran Rule: How 38 USC 1154(b) Relaxes the Evidence Standard

Quick summary
Combat rarely leaves a paper trail. Under 38 USC 1154(b) and 38 CFR 3.304(d), a combat veteran's credible account of an in service event is accepted if it fits the circumstances of service, and VA can reject it only by clear and convincing evidence. This article explains what the combat rule proves, what it does not, and how to use it.

Combat veterans often abandon claims because no record of the firefight or the blast exists. That is the exact gap 38 USC 1154(b) was written for: satisfactory lay evidence consistent with the circumstances of combat service must be accepted, and VA can rebut it only with clear and convincing evidence. What the rule does not supply is the diagnosis or the nexus. Those still get built the normal way.

Why the combat rule exists

Combat rarely leaves a paper trail. Firefights, blasts, and the chaos of a forward area do not pause for someone to write a record. Congress recognized this. Under 38 USC 1154(b), a veteran who engaged in combat is given a relaxed evidence standard for proving that an injury, disease, or stressor event happened during that combat service. The implementing rules are 38 CFR 3.304(d) and, for stressors, 38 CFR 3.304(f).

This article explains what the combat rule does, what it does not do, and how to use it.

What the rule says

If you engaged in combat with the enemy, VA must accept your satisfactory lay or other evidence that an event happened in service, even if there is no official record of it, as long as the account is consistent with the circumstances, conditions, or hardships of your service. VA can reject it only by clear and convincing evidence to the contrary, which is a high bar.

The Federal Circuit laid out the test in Collette v. Brown, 82 F.3d 389 (1996), as three steps:

  1. You submit satisfactory lay or other evidence that the event occurred in service.
  2. The evidence is consistent with the circumstances, conditions, or hardships of combat service.
  3. If steps one and two are met, the event is presumed to have happened, and VA may rebut that presumption only with clear and convincing evidence.

In Reeves v. Shinseki, 682 F.3d 988 (2012), the court confirmed that the rule helps prove the in service part of a claim, that is, that the injury or disease was actually incurred during combat, not only that a general event occurred.

Limits of the combat rule

This is the part that trips people up. The combat rule lowers the bar for one element only, whether the event happened in service. It does not prove the other two elements of a claim:

  • It does not prove you have a current diagnosis. You still need a present disability.
  • It does not prove the medical link, or nexus, between the combat event and your current condition. You still need a medical opinion or a recognized presumption for that.

So the combat rule gets you past the question of whether it happened. You still build the diagnosis and the nexus the normal way.

Who counts as a combat veteran

There is no single badge that settles it, but VA looks for evidence that you personally took part in events that amount to combat with the enemy. Combat awards, such as the Combat Infantryman Badge, Combat Action Ribbon, Combat Action Badge, or a Purple Heart, are strong evidence. Hostile fire or imminent danger pay records, unit histories, deployment orders to a combat zone, and credible lay statements can also support it. If you have no combat decoration, a clear and specific account of the action can still carry weight.

How to use the rule in your claim

  1. Show the combat. Point to a combat award, a hostile fire or imminent danger pay record, unit histories, or a specific account of the action.
  2. Describe the event plainly. On VA Form 21-4138, state what happened, roughly when, and where, in your own words.
  3. Tie it to the claim. Name the injury, disease, or stressor that came from that event.
  4. Then build the rest. Add the current diagnosis and a nexus opinion, because the combat rule does not supply those.

For a stressor in a PTSD claim, 38 CFR 3.304(f) provides a related path. If the stressor is related to fear of hostile military or terrorist activity and a VA examiner confirms it, the stressor can be conceded without independent verification.

This is educational. It is not legal advice. A VA accredited representative can help you frame a combat claim and decide which evidence to lead with.

Common questions

What does the combat veteran rule in 38 USC 1154(b) do?

It relaxes the evidence standard for proving that an injury, disease, or stressor event happened during combat service. VA must accept your satisfactory lay evidence that the event occurred, even without an official record, as long as the account is consistent with the circumstances and hardships of your service. VA can reject it only with clear and convincing evidence to the contrary.

Does the combat rule prove my whole claim?

No, and this is the part that trips people up. It lowers the bar for one element only: whether the event happened in service. You still need a current diagnosis and a medical nexus opinion linking the event to your condition, unless a recognized presumption supplies the link.

How do I show VA that I engaged in combat?

Combat decorations such as the Combat Infantryman Badge, Combat Action Ribbon, Combat Action Badge, or a Purple Heart are strong evidence. Hostile fire or imminent danger pay records, unit histories, and deployment orders also support it, and even without a decoration a clear and specific account of the action carries weight.

How does the rule help a PTSD stressor?

Alongside 1154(b), 38 CFR 3.304(f) provides a related path: if the stressor is related to fear of hostile military or terrorist activity and a VA examiner confirms it, the stressor can be conceded without independent verification. Describe the event plainly on VA Form 21-4138, then build the diagnosis and nexus the normal way.
