1/35 British Challenger 2 TES Main Battle Tank w/Workable Track Links.

Vickers Defense Systems began developing the Challenger 2 tank in 1986 as the replacement for the Challenger 1. Although the majority of the tannk was not changed significantly, the turret was redesigned, and the main gun was changed from the L11A5 to a new L30A1 55-caliber 120mm rifle. The TES (Theater Entry Standard) is equipped with slat armor and new ERA (explosive reaction armor). Combined armor has also been added to the lower front of the tank based on combat experience. 

This kit from Rye Field model features pre-assembled crawler tracks, an openable main hatch, and photo-etched parts and decals too.
