It depends on who you're playing with, and who is doing the writing, but certainly open rolls and drags based on a 16th note rhythm, especially 5s, 6s, tap 7s, and 9s; and paradiddles, double paradiddles, and paradiddle-diddles; and flams on everything, flam taps, flam accents, Swiss triplets, and maybe pataflaflas and flam drags. And lots of accented 16ths. I never encountered an actual flamacue or ratamacue in my marching career, but maybe somebody is still playing them. I wouldn't go off of the list of the standard 26-- some of them are given in an old-fashioned form, which isn't going to help you much preparing for contemporary marching settings.
