The Bastion G-20 class SPG is a later industrial era TL-6 Armored Fighting Vehicle.

Description (Specifications)[edit]

Enlightened 6T class tracked 20 cm SPG, TL-6: The vehicle's hard steel armor sheaths the chassis and turret to levels of protection to protect versus bullets and shell fragments. The top of the vehicle has the best armor to shield from over head strikes from indirect fire from counter battery missions. This design is sealed with over pressure for the crew in protected forces roles and to permit amphibious operations. An improved internal combustion power plant and transmission are linked to a large tracked suspension with low ground pressure to avoid becoming bogged down in sand, snow, mud or soft soils. The coaxial HMG can help deal with encroaching infantry, the TAC missile system can help versus air craft and light armor. The wire guidance restricts it to 4km range. The main gun is versatile and can engage in direct fire and its primary mission of indirect fire and artillery support. It is not stabilized to fire effectively on the move.

The vehicle has a crew of twenty one: driver, gunner, 18 loader/gun crew and commander.
