Hey, of course I'll provide you with the banner design :)
These are the two banners for the front:





And hey, you don't bother me and this didn't take a lot of time, so it's all fine ^^

Sure, no problem :)

The abrams is very similar to the leopard 2 shapewise, so I guess you'd be good to go if you took my Leopard 2 Main Battle Tank and built it with sandstone. Move the bore evacuator one block forward and replace the far right and far left ladder on the rear with oak buttons. Replace the dark oak fence gates on each side of the turret with birch or oak fence gates and add 3 opened birch or oak fence gates at the rear end of the turret just like on my Merkava Mk 4 Main Battle Tank design. That should give you a pretty good abrams already.
