Abstract: A light-weight anti-tank weapon for use by infantry consists of a launching tube for a projectile such as a rocket contained either directly in the tube or in a container which, when firing takes place, forms an extension of the tube. To enable the weapon to be used either by a right-handed or left-handed marksman, the fittings associated with the weapon are symmetrical in relation to the longitudinal plane when the weapon is ready to be fired, and certain elements of the weapon, particularly an optical aiming device and a shoulder-piece, can be secured to one of the two sets of suitable supports or mountings in the right-hand and left-hand positions, respectively.

Abstract: A projectile-firing weapon wherein the firing of the projectile is brought about, at least partly, by the unfolding of a flexible bag under the effect of a pressure within the bag.
