  GIUK Gap Greenland-Iceland-UK Gap.

  GPMG General Purpose Machine Gun.

The L7A2 GPMG, or 'GIMPY', is a 7.62x61mm belt-fed general purpose machine gun. The GPMG has been in service with the British military for decades. The GPMG can be carried by foot soldiers and employed as a light machine gun (LMG), although it has largely been replaced by the lighter 5.56x45mm minimi in this role in most regiments. Not willing to give up the GPMG's stopping power for convenience, Paras, marines and UKSF still lug the weapon around on foot patrols. A fold-out bipod is used to support the GPMG in the LMG role. The GPMG is more commonly mounted on vehicles, helicopter, boats and in fixed positions. When mounted on a tripod, with C2 optical sight added and with stock removed, the GPMG is used in 'sustained fire' (SF) mode. In SF mode, the GPMG, with a 2-man crew, lays down 750 rounds-per-minute at ranges up to 1800 meters. UKSF, Paras and Royal Marines put the GPMG on their WMIK Land Rovers. The SAS have been known to have up to 3 GPMGs mounted on one vehicle. The 'beating zone' suppressed by multiple GPMGs is phenomenal.


  HE High Explosive.

A high explosive round is a hollow casing containing an explosive compound. Set to detonate on impact or at a selected altitude, it is useful against infantry and some larger targets. It is the least expensive (and thus most common) indirect fire round used.

  HEAT High Explosive Anti-Tank.

A hollow shell filled with explosive compound. An inverted cone in the nose of the shell directs the explosive force forward into a high energy jet of super-heated gas and molten metal, reducing the effectiveness of the round against soft targets but vastly increasing it against armor.

  HEDP High Explosive Dual Purpose.

A hollow round containing an explosive compound filler with a shaped charge director in the nose to provide the round with an enhanced armor penetrating capability.

  HEPXPF High Explosive Proximity Fused Pre-Fragmented.

A sophisticated air defense round also useful against personnel on the ground. It is a high explosive round with a reservoir of tungsten pellets which become lethal fragments when the round is detonated. When used against aircraft the proximity fuse detonated the round when it approached within 6 meters of the aircraft.

  HESH High Explosive Squash Head.

A type of chemical-energy anti-tank round. On contact, plastic explosive is squashed against the surface of the target and detonated

  HMMWV High Mobility Multi-purpose Wheeled Vehicle.

  ICM-DP Improved Conventional Munitions, Dual Purpose.

Similar to ICM, the ICM-DP round contains shaped charge grenades which have an improved effectiveness against armored targets, provided they achieve a direct hit.

  ID Infantry Division.

Sense the Transition to Brigade Combat Teams the actual use of the Division has gone in History. But as Commands are concerned there is a Division to answer to. For the most part this Unit Size is no longer deployed as a whole. From now on it will have units all over the World at times and at some times it will in CONUS.
