Might be inspired by an episode of MS IGLOO that had an entire squad of Federation-captured Zakus (supported by Type 61 MBTs like the one in the foreground) wreaking havoc on Zeon supply lines.
Those two barrels just annoy me whenever I see them. What is the point of having two barrels when that just increases the complexity of the tank?
Do you know that long time ago, some had consider making dual turrets to some real life tanks to increase firepower. However it was too complex and an engineering nightmare to be done.
