Ramming Speed!

Earth- (BiS) While starships and spacecraft are nice and all, nothing in the sky can match the brute force a tank can have on the ground. Massive weapons capacity, sheets upon sheets of armor, vehicle storage, and troop carrying capacity are all some of the great advantages to tank use. This lil' guy has the design of a tank, the slickness of a sports car, and the armaments of Rambo after a 50% off sale at the Weapon Store. The radar array on top is also worthy of note, as well as the excellent use of the Technic joint connectors.

Jupiter- (BiS) Ever since seeing this amazing MOC by nate_daly, I've wanted to pay it some sort of tribute.The excellent striping, integration of dark green parts, and ridiculous amounts of SNOT add up to make what looks to be one of the most swooshable spacecraft I've seen in a while! Also, this double cockpit idea seems to be gaining quite a bit of popularity recently, maybe it's no accident....
