O Neg Cloth Patch
Modern British forces blood type tactical patch on velcro for O negative, the latter of which can be given to any patient in an emergency so is of particular value (The Quartermaster's boss (Mrs F) has so far given 56 pints of O negative). I guess if a soldier is wounded it is also important to know that they are O negative, as they can only receive their own blood type or plasma. Soldiers are more likely to know their blood type than those in civvy street for obvious reasons.
