The '''Gun Emplacement'''''Half-Life Prima Guide'' is a stationary turret fully protected by sandbags, and used by the HECU in Sector E Materials Transport.
*Manned by a single soldier, this emplacement consists of two cannons that fire rounds extremely fast, used behind sandbags to provide fire support and fortify crucial Materials Transport locations, such as the door to the topside area of the High Altitude Launch Center, the tracks near the root of the rocket, and a small triage area.
*It is sometimes used along a Tripod-Mounted Heavy Machine Gun.
*Defeating it is difficult, as firing most weapons at the front opening is ineffective. The most common way of destruction is a well placed grenade, or other explosives. It will kill the soldier behind, stopping the weapon.
As the weapon is a brush using the entity "func_tank", the HECU soldier located behind is actually idle.
