Hi i have begun using a Vietnam deck but i found out we are missing one important version of the Sheridan aka "Two Box M551"
( With the obvious shortcomings of the Shillelagh missile, all but two of the guidance and fire control components of the missile system were removed (the power supply and rate sensor were retained. These were needed for stabilized turret operation.). The resulting additional space was filled with two separate boxes, one for 7.62x51mm NATO ammunition (coaxial machine gun), and one for 12.7×99mm BMG (.50 cal) ammunition, and the missile stowage was redesigned to accept conventional rounds)
Basically throw away acc 4 missile for extra rounds like the Topas 2a/ap
