A soldier may be entitled to Imminent Danger Pay (IDP) when serving on official duty in an area designated by the Department of Defense as eligible for IDP. The same entitlement amount is also received by meeting different eligibility requirements that qualify a soldier for Hostile Fire Pay (HFP). This entitlement is usually listed together as Hostile Fire Pay/Imminent Danger Pay. A soldier can receive IDP or HFP but not both.

Retired Soldiers are not eligible for Imminent Danger Pay or Hostile Fire Pay.
