AJAtcho 623 Report post Posted March 21, 2019 3" Gun Motor Carriage M5. This is an early version of the 3" GMC M5. Many changes to stowage and the crew's positions were made during development, and a blast deflector, shields for the crewmen seated in front of the gun shield, and a rear stabilzing spade were eventually fitted. (Picture from Tank Data, volume 2.) The 3" GMC M5 was based on the Cleveland Tractor Company's (Cletrac) seven-ton high speed tractor MG-2. The 3" gun M6 was ballistically identical to the 3" gun M7 later found on the heavy tank M6 and 3" GMC M10. The only armor on the vehicle was provided by the gun shield and two small shields in front of the driver's and assistant driver's/gunner's positions; these men sat in front of the rear-mounted gun during travel and therefore would have had no protection from the gun shield. With the gunner's seat in place, traverse to the right was limited to 18°. The project was begun in December 1940, and the vehicle was standardized in January 1942 with intentions to procure 1,580 carriages. A protracted development period--during which the vehicle's estimated weight increased by almost 50%--as well as problems with reliability, structural integrity, small ammunition load, and track failures led to the cancellation of the project in August 1942 before production had actually started. At that point, work on the M10 was far enough along that the first production examples of this much more successful vehicle were accepted the next month.

AtomicPope 3,953 Report post Posted March 30, 2019 This would be a great addition to the US tree, which is lacking high punch guns in lower BR. This could be a decent Marder equivalent below the M10 and a nice uptier insurance. Share this post Link to post Share on other sites More sharing options...

A few were still kept in the US and there are lots of vehicles in tech trees that never saw combat or only had a few built. We also have Shermans for each nations....

TheTurtleTanker 1,167 Report post Posted March 31, 2019 5 hours ago, Conraire said: That's because all 962 were shipped to Russia So how many Magach 3s did the US operate? How many TAMs did the Germans operate? How many Strv 81 (Rb.52)s/Sho't Kal Dalets did the British operate? Also, at least according to Wikipedia (so not the greatest source), the US actually did retain 282 (so not all 962 were shipped to Russia) but got converted to half-tracks. So would it really be odd for the US to have it as a premium vehicle? Spoiler Share this post Link to post Share on other sites More sharing options...

Same reason the Su-57 is in the Soviet tree - it served with a major power, not with a country not represented - TAMs and Magach etc - well those countries aren't in the tree - Soviet Union is.
