The T26E4 is a tier 8 American premium medium tank. It have several layers of aditional armor on front which add roughly 140mm of spaced armor layered in 2 extra plates. It is a rather slow tank with little to no side or rear armor. Keep this in mind while driving this tank, as the more than protected front will bounce many incoming shots.
This tank is armed with a 90mm gun with sub-par penetration. Furthermore the damage per shot, (240 average) is also sub-par.
This tank is no longer avalible in-store as of patch 8.6 and has been removed from the game for an undefined amount of time.
