Looking at the latest M1A2 SEPv3, & in anticipation of the first Australia’s new Abrams arriving in 2024, I’m after some details on the commander’s cupola of this variant.
Bottom line: how tall is the spacer, inside the red box?
The plain Jane M1A2 had the “improved commander’s weapon station” with a flex mounted .50 cal that couldn’t be fired from under armour. Once CROWS was introduced, the mounting plate over the Gunner’s Primary Sight meant that the cupola had to be raised.
Looking at this picture, you can see there are no spaces between each periscopes, so is really hard to tell without actually looking at the Commander’s station.
