Have all your party members disguised as Senate Commandos in Hostage Crisis. (Story mode only).

In Hostage Crisis stage, all you have to do is kill the Senate Commandos, they’re the Blue guys with helmets. Once you kill them they will drop off their Blue Helmets. Just pick up the Blue Helmets and wear them to each of your character.
