It depends what you're fighting and what role you want it to play. Tank buster, heavy infantry killer, light infantry killer. Tank buster, las cannon/assault cannon for lighter armor. Heavy infantry, assault cannon/auto cannon/plasma cannon. Light infantry heavy bolters/assault cannon.

The Schneider Assault tank, The Renault FT- 17 light tank, The Saint Chamond Assault Tank, and the Char 2C Heavy tank. These are the main tanks, however there were a few minor tanks as well.

Cage, or I called my tank simply a tank.

I am not sure I quite understand your question. Why put tortoise eggs in a water tank?

The M6 Heavy Assault Tank was a prototypical tank built in WWII. It was a designed on the base chassis of the failed T1 Heavy tank. It was armed with a 90mm M10 cannon, had 130mm armor, and the original T1 chassis. The M6 was designed in response to the rise of the new Tiger and Panther tanks. However, it was bulky and unwieldy, with a huge silhouette, and as such was unsuited for combating the Tiger tank. It was never designated as a Super Heavy tank.

Aside from the M6HT, no other tank was designated with the name "M6".
