hi Freebird
Welcome back, we have missed you, hope everything is well for you.
Indeed the Ram tank series were a missed opportunity, and the design was a very fine one indeed. But whilst the British Tanks of the period had their faults, they were not failures per se. What caused the repeated British defeats was not the inferiority of their equipment, it was their atrocious tactics and total misuse of their armour.
Contrary to what most people think, Tanks are not the best weapons sytem to engage other tanks, and you dont use ones tanks to chargee, cavalry style, the enmies position. Rommel had this type of madness completely covered ....he would use his limited tank numbers to lure the British tanks out, and draw them over his AT screen of 88s and 50mm guns. That British Taanks would oblige and generall attack, unsupported just made the whole thing an even bigger slaughter. British Armoured Divisions had far too little in the way of indigenous support, and this continued until the latter part of 1942. Once the British realized how to support their armoured formations properly, the superior numbers, and massive artillery advantages within the division, made a British armoured Division a very potent weapon.
RAM Tanks were not actively deployed, but the hull was used to build the Sexton SPG, which I think was far superior to the M7 Priest that it supplanted. Rams were also used in a turretless form as Kangaroo APCs, which offered far better protection to the Infantry than any other APC that I know of for the period. RAMs also were used as ARVs and as mobile observation posts with a turret but a dummy gun. These were attached to the Sexton Batteries in Europe.
