These soon got replaced with recoilless systems with the application of the shaped charge explosive projectiles during the second world war. Portable anti-tank systems initially appeared in the form of heavy rifles – so called anti-tank rifles – during the first world war and interwar period. Examples include, Bofors Bantam, BGM-71 TOW, 9M113 Konkurs, Panzerfaust 3, 9M133 Kornet, etc. Semi-disposable systems, where the launcher is manufactured pre-loaded and issued as a single unit of ammunition meant to be launched from a reusable firing and sighting device and discarded after one use.Examples include: Bazooka, Panzerschreck, Carl Gustaf 8.4 cm recoilless rifle, RPG-7, Panzerfaust 2, etc. Reusable systems, consisting of a reloadable firing system onto/into which a rocket or cartridge is loaded, operated by one or two soldiers.Examples include: Panzerfaust 1, M72 LAW, Miniman, AT4, FGM-148 Javelin, NLAW, etc. Disposable systems, consisting of a small pre-loaded, single-shot launch tube meant to be disposed after firing, operated by one soldier.MPATS-launchers can be either unguided or guided weapons and generally fall into three distinct categories: Man-portable anti-tank systems ( MANPATS or MPATS) are traditionally portable shoulder-launched projectile systems firing heavy shell-type projectiles (although throwing and lunge weapons have existed), typically designed to combat protected targets, such as armoured vehicles, field fortifications and at times even low-flying aircraft (especially helicopters).
