Panzer Panther, Ausf G
A knocked out Panther inspected by the British, note the distinctive "flammvernichtern" - flame dampers, fitted to the end of the exhaust pipes. In the latter part of the war the panzers fought mainly from concealed positions to avoid allied air superiority and fire flashes emerging from the exhaust pipes would give away their hide out to the enemy, hence the introduction of the flame dampers.
