It brings to my mind "PICMDEEP", that crowd-favorite machinegunner's acronym. There, the "P"s stand for "pairs", as a reminder to employ machine guns in pairs, and "protection", to keep in mind the safety of the machinegun team, but I'd like to think one of them could also stand for "positive mental attitude".
