One thing we were always taught was in any situation there's a solution, and not to "...give up until the ... water is coming in the people tank!" So to overcome the 152mm storage issue is not a problem, we (I) just have to think about the last (served until 1996.) "modern" era tank that was armed with a 152mm gun, carried 20 rounds plus 9 ATGW and weighed in at slightly more then 1/4 the current weight of a front line MBT. So with pics
I present the last Light Tank to serve with the USA.
USA/1968/M551 Sheridan/C4/152mm (20Rs),MGM-51 Shillelagh (9),
AA 12.7mm (1KRs) & 7.62mm (3KRs).
The design was "innovative" and served it's purpose to a degree but it had many issues which lead it to be replaced by the M60A1 and eventuaaly the M3 Bradley for the Recon role.
