The Winter Soldier (abbreviated as W.Soldier for short) is a playable unit in Metal Slug Attack, first appearing in the Extra Ops titled "Santa Trap". As this Extra Ops has completed, parts can only currently be obtained through the occasional Rebel Army Event Crank. He boasts decent health for his low AP cost (with his additional special-summoned snowballs soaking yet more punishment), in turn dealing light (but rapid) damage. He is invulnerable to both knockback and stun attacks.
