Greg and Stephen have come up with some believable armor upgrades in their
Antipodal Armoured Collaboration thread.
I really liked this tank:

and procured the gun from Sprue D of the Hobby Boss 1/35th Scale IDF Merkava Mk. IIID that I got from ebay. The tank itself is the Meng 1/35 Leopard C2 MEXAS w/Dozer blade. A great kit - it goes together quickly, well and logically engineered and good detailing.
I started it yesterday:

and with a few interruptions along the way, i was this far by 5 PM:

The vinyl tracks are fine. There's a long OOP workable track set from Meng, but it's not worth hunting it down. Everything has fit well so far, and from looking ahead, the rear of the body may need some putty, but not much. I also put together the Hobby Boss 120mm IMI MG251 barrel. It needed some work and will probably need some extra detailing, but i think the hardest part of this build will be getting a good match for the weathered NATO/CARC green camo.
