The Russians demanded that diesel engines be installed in the thousands of Lend-lease tanks we gave them.
Yes, the folks at Warren, in about 6 weeks, figured a way to mount two Detroit 6 cylinder 71 series diesel engines side by side on the engine compartment of the A4 tank. This became the A4M2 version of the Sherman tank. We shipped the Soviets over 6,000 of these diesel powered Shermans. As a side item. the US Marine Corp also used this diesel powered version of the Sherman in the Pacific Theater.
