I got my Assault Tank today as well (ordered from EE). This thing is practically a model! I’ve collected the 21st Century Toys and BBI 1/18 scale armored vehicles for years and those were basically highly detailed preassembled models with a level of detail that far outstripped most Star Wars toys... The Assault Tank is the exception

The vehicle is loaded with working features and (thankfully) sidesteps any gimmicky features like firing missiles, sound effects, etc. Basically the functional aspects are as follows:
Working treads
Rotating main cannons
Swiveling secondary guns
Removable deck plates for cargo bed
Foot pegs for figures to stand in cargo bed
Two solid kyber crystal transport containers
One container that opens & has two crystal cylinders that open to reveal kyber crystals
Opening drivers hatch
Opening engine cover with detailed engine
Opening commander’s hatch
Removable front cover to access interior
Interior features seats, steering controls (driver’s controls move) tons of switches, circuitry, etc. Even the backside of the removable front panel is detailed with cooling fans and circuitry
I’ve got mine crewed with some of the Black Series Scarif Trooper figures at least until I can find some of the new Assault Tank Driver figures in the next TVC figure wave... Overall I am very pleased with the Imperial Assault Tank and hope we get more Vintage series vehicles in time.
