NKA

It is SOP for soldiers in combat situations to have their blood type readily visible on their uniform, so that if blood transfusion is required, time is not wasted deteriming blood type. Some units also require any allergies to be visible, and if the Soldier has No Known Alergy (NKA) this info is stated. This is commonly seen on Rangers, Special Forces, Navy SEALS and other elite forces.

A soldier that has ''NKA'' sewn on his uniform has no known alergy.
