The contract is standard. . .you are operating under contract with the DoS and therefore are supposed to receive medical aide. . .you are, after all, helping the DoS. This is a standard Term and Condition of the IDIQ SS contract.
And yes, you are NOT covered by LOAC like soldiers are as you are a civilian and therefore can’t take up arms or engage in combat. . .you would them be an illegal combatant and subject to prosecution under local laws.
DOS contracts are not standard, at least not these days, although I was not operating under some DOS contract, just a MOA with DOS, DoD and the White House.
