Hmm, the player's mech already have smoke dischargers.
From what I can tell, the smoke dischargers mounted on the sides of the turret look more like the type that deploy smoke around the mech itself, while the smoke grenade version that we use works more like a mortar, firing smoke rounds to create a smoke screen at a distance.
Because of that, maybe it would make sense to make the built-in smoke dischargers a default defensive system (close-range, self-cover), and let the equippable smoke launcher focus on its unique role as a long-range smoke deployment tool?
