UT-AT

Unstable Terrain Armored/Artillery Transport

based on unreleased LEGO set

The Unstable Terrain Artillery Transport (UT-AT), also known as the "Trident," was a military transport and assault vehicle that served the Grand Army of the Republic during the Clone Wars when the use of walkers was unsuitable. Though slow and vulnerable, the vehicle was adept at crossing bridges and traversing unstable terrain, but due to its elevated position it was constantly prone to enemy attack. Alternate configurations of the UT-AT were stocked with bridge laying equipment, converting the transport into an effective trail blazer. (via Wookiepedia)

This set was based on the picture that can be find in 2016 LEGO Star Wars Visual Disctionary. I tried my best to make it feels like it is 2010 build. Inside, you can find 4 places for gunners and a pilot. Main cannon is moveable, just like the other small ones. Right and left cannons are stable.
