I love the look of the Lee/Grant, its big and bulky and just.. interesting! plus was used in the desert by the US and British, the pacific, and the Russians for lend lease, so plenty of options for users.
Design commenced in July 1940 and the first M3s were operational in late 1941. The U.S. Army needed a good tank and coupled with the United Kingdom's demand for 3,650 medium tanks immediately, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible. The M3 had considerable firepower as it was well armed and provided good protection, but had certain serious drawbacks in its general design and shape, such as: a high silhouette, an archaic sponson mounting of the main gun, riveted construction, and poor off-road performance.
Its overall performance was not satisfactory and the tank was withdrawn from front line duty — except in the remote areas of the Asian Theater where it was used by British forces until mid-1944 or possibly later — as soon as the M4 Sherman became available in large numbers. In spite of this it was considered by Hans von Luck (a Colonel in the Wehrmact and author of Panzer Commander) superior to the best German tank at the time of its introduction, the Panzer IV.
On the back you get a clear image of what the finished model "should" look like.
