It would help to be more specific if possible. What legion were they from? Where are they stationed? What are they doing at the time? Are they veterans/officers or just raw recruits?

Edit: For a general answer. Most legionaries would be wearing something like this during Hadrian's reign. A centurion would look more like this. Roman cavalry and auxiliaries could wear hamata or squamata (chain or scale respectively) and used a longer sword called a spatha with a spear.

Important small details. There is a dagger, called the pugio on his left hip. A normal soldier would always have his gladius (primary weapon) on his right hip. A centurion wore his sword on the left hip. Legionaries would also carry two pila, or throwing spears. One was usually lighter than the other. They were intended to be thrown, but the larger was also used in melee combat if necessary.
