During the 6-day war, the AMX clashed withthe T-54/55s. The AP
shells from the 75mm gun bounced off the hull of the T-55s.
This is true, the original AP rounds fail to penetrate the
T-54/55 armour during tests. Therefore Singapore develop the APFSDS
round which have much better penetration. It have such high recoil
due to the great velocity that the SM1 can hardly take it since its
not originally designed to fire such high velocity
ammunition.
I don't think it is a good idea to reveal tactics for the SM1 crew
against MBTs but i have to say that the venerable SM1, is not
totally helpless against MBTs. It is after all used to provide
additional fire support for the Ultras and BX in a ABG. We have
other assets such as the Longbow Apaches for the MBTs.
