The 3.7cm PaK36 anti-tank guns served with distinction in the early campaigns of the war and could be armed with the new Stielgranate (stick grenade) ammunition.The Stielgranate 41 is a projectile which was attached to the end of the PaK36's gun barrel and when fired at a close range had the general equivalent impact of a 7.5cm PaK40 shell giving these guns a new lease of life.
