ESF-T 43 Jack O

The ESF-T 43 Jack O or T43-O was an experimental variant of the T43 designed by Altenor Forge Works for Operation Overlord. Its main feature was the replacement of both the 9cm main cannon and 78mm Howitzer with a 155mm long-ranged anti-airship cannon. Besides its cannon, the tank also feature stripped armor for speed and two extending stabilizers for recoil. The tank's large armament and the recoil associated with it required the tank to "dig itself in" with stabilizers to shoot accurately. This made it an easy target for Fighter Airships. Cooling systems within the tank and the auto-loading mechanisms replaced two of the three crew-members required for the normal T43 and the T43-O only required one person to operate it. The T43-O entered service in mid Imperial Year 9993 and only had a production run of thirty units, most of which never saw combat.
