Each legion was broken into several fighting groups.
A legionary's uniform included a rectangular shield, a short sword, a dagger, a metal jacket, a belt, a helmet, a kilt, a shirt, and hobnailed sandals. The legion wore special hob-nailed sandals. Unless they wanted to sneak in quietly, a legion on the move was impressive!
