The tank is actually a U.S. built M2A2 light tank that was given Lend-Lease to the Brits.  The M2A2 was soon replaced by the M3-series of light tanks.  These tanks were very popular with the Brits and used by them very effectively in the Western Desert campaigns against the Axis in North Africa.  These light tanks were called "Honeys" by the Brits and were powered by aircraft radial engines.  They weighed in at about 15 tons. 

 

These light tanks were used like cavalry troops -- to do recon and able to fight when necessary.  They were heavily armed (for the time) with up to five (5) .30 Browning machine guns and a 37mm cannon.  The cannon could fire AP, HE, and cannister (a kind of shotgun round used against infantry attack).

 

The U.S. Army used the M3-series, and follow-on M5-series, of light tanks in all theaters of the war for scouting and fire support for the infantry.  In Europe, the M3 and M5 were out-classed by the German armor and would avoid fights with them for good reason.  In the Pacific and China-Burma-India theaters, the M3 and M5 were well-suited to fighting the Japanese whose tanks left much to be desired.  The M3 and M5 were replaced by the M24 that saw limited WW2 service and was used post-war by the U.S. and its allies, and in Korea.
