Wow TubaMan is a high school student. Colleges also have marching bands. Marching bands don't hold a candle IMHO to drum corps, which dispense with the puny woodwinds in favor of more brass and percussion instruments, so they are a hell of a lot louder. Both marching bands and drum corps use specialized percussion instruments like marching snares, tenor drums/tenors, and marching bass drums. Baritones are different for marching, too.
