From: Old Los Angeles pre-1960
I was wondering if I was in the wrong forum! interesting..
As far as M-4 medium vs T-34, pros and cons for both.
T-34 has better shaped armor - getting better protection from thinner plate, T-34 has wider tracks and somewhat lower ground pressure for poor traction conditions. T-34 has a diesel engine (unless I don't recall correctly) so somewhat less fire hazard potential. Russian armor plate was fair to very good quality depending upon year produced (later was better as I recall).
M-4 Medium - better mechanical finish, more mechanically reliable than any of it's contemporaries, so more will complete the march to to the combat zone.
75mm gun M3 on M4 Medium has a better AP shell (much more consistent in quality control for WWII - and by all published accounts - better AP performance), and greater ammo load.
M4 Medium main armament will have gyro-stabilization - not perfected, but useful.
M4 Medium has a functional radio, M4 Medium has a higher silhouette (by a small percentage) - but also a greater M/A depression for a better hull-down position.
Speed is about equal - the 21 mph quoted above was for sustained road march, sprint speed was about 30mph.
Crew efficiency - M-4 Medium has a 5 man crew compared to a T-34's 4 man crew, so there is a better distribution of duties in and crew efficiency in an M4.
Armor quality on an M4 - early models had notable numbers of tanks with sub-standard plate for cast, and M4 welded hull models - prior to late 1943, had a poorly designed glacious plate with too many weld joints. But all M4's produced from late 1943 onwards had good quality armor for thickness.
T-34/76 vs Tiger I, Tiger I advantage in a 1 on 1 engagement. M4(75) vs Tiger I - same.
T-34/76 vs Panther, depends on range, but greater room to maneuver favors the T-34/76. M4(75) vs Panther - same.
T-34/85 vs Tiger I, depends on range, but greater room to maneuver favors the T-34/85. M4(76) vs Tiger I - same.
T-34/85 vs Panther, depends on range, but greater room to maneuver favors the T-34/85. M4(76) vs Panther - same.
Numbers produced - significantly more M4 Mediums ...than any other WWII tank.
When T-35/85 met M4 Medium(76) in Korea & Middle East- M4 got the better, but that's attributable to training.
Overall - it's anyone's call...kind of depends on who is driving them, how many you have, and just how good your supporting arms are.
