10. A motorized infantry regiment is equipped with the same kind of light and heavy infantry weapons as an infantry regiment. Some of these weapons can be fired from the personnel carrier. These are:
(a) A light machine gun in the antiaircraft pivot mounting,
(b) A light machine gun in the armored shield,
(c) A machine gun on armored mounting with telescope,*
(d) A heavy mortar.*
11. Firing from the carrier increases the effectiveness of the weapons. This improvement is due to the greater mobility, the constant readiness to open fire, the armor (which affords protection against enemy infantry fire), and the greater accuracy of fire.
12. The 50-mm antitank gun and the heavy infantry gun fire from self-propelled mountings.
13. The cross-country performance and armor, of this vehicle, together with the possibility of fighting from it, make the armored personnel carrier the chief fighting agent of motorized infantry. It can cover long distances rapidly and at the same time conserve the energies of the men. It can travel on all roads in any season. Its fording, climbing, and crossing abilities combine to give a high cross-country performance. Providing the ground is firm and level, the normal road speed can be maintained off roads and tracks. Its armor gives protection against small-arms fire, light infantry weapons, and shell splinters. The vehicles can therefore be brought up to the battle area and moved about under fire from enemy infantry.
