 The 75 mm M6 is an excellent anti-tank weapon at Rank II-III where it is usually utilized, and is able to still perform decently far above its tier. As with any gun, knowing your enemy's strong points and weak spots will allow you to use this gun effectively. Good muzzle velocity, armour penetration, and post-penetration damage with the M61 APCBC shell allows this gun to defeat many enemies in one shot, especially medium and light tanks. Check "Available Ammunition" for recommendations on what shells to use with this gun and how.
 '''M24 Chaffee:'''
-When mounted in an M24 Chaffee turret, the 75 mm M6 has access to a vertical stabilizer. This means that the M24 is able to vertically stabilize the gun for accurate firing very quickly. Depending on the circumstances, a stabilized M6 cannon can outperform  on the move any other tank gun previously mentioned which does not have a stabilizer.

 An attempt was made to improve the 75 mm M6 gun in early 1945 with the 75 mm gun T21. The new gun featured a stronger breech assembly, improved firing mechanism, a fixed breech operating handle, and a hand cocking lever for the gun that was accessible to every turret crew member. The gun also featured a T13 single-baffle muzzle brake. The gun was eventually accepted as the 75 mm gun M17, but the war had ended by that point and so did the M24 production lines.<ref name="StuartHunnicuttpg3">Hunnicutt 1992, p.230</ref>
