The M2 Light Tank is a Tier II American Light Tank. Fast and swift and equipping a decent gun, it makes a good scout and has a low number of hit points, so run away when you have spotted enemies unless they are similar to you. It does have well sloped armor but anyone can penetrate it since the nominal amount is small.
