The Anti-Tank Rifle is a British anti-tank weapon only ever used by sappers during the Tiger Ace campaign, aside from being a nuisance, it has near no effect against the tiger. Despite this, it can still do some damage and can be very annoying when in the rear and the tiger is in a breakdown as shown below.
