Captured Tiger II Tank

A GMC mounting the British 57mm 6-pdr gun. The gun (towed version known as the 57mm M1 ATG) was a US-made licensed copy. The gun was designed for use by the UK, but most wound up being shipped to the USSR as lend-lease weapons. US military designations used the "T" (test) to designate weapons before being accepted into service as an "M" (model).
