The GLCS is a 4 barrel two caliber pistol firing 20mm RAM grenades. The weapon is loaded by inserting the grenade in the front and click it into place. The pistol got a simple grip and each pull of the trigger will fire one barrel. It is possible to load each barrel with different round, but the firing will always be in same order. With some luck you may actually need the particular round which are currently ready if different rounds are loaded. Reload time is 10 seconds for all 4 barrels.

The name suicide gun was dubbet after a series of accidents where operatives accidentally fired the pistol while reloading, resulting in blown off heads in the more extreme cases. The loading and security mechanism was improved quickly. Unless the weapon safety lock isn't engaged the weapon won't fire if there is a grenade in any barrel which hasn't been loaded properly. And in addition the grenade won't lock into place unless the safety is on.

The GLCS comes with seceral types of rounds, however HE, HEAP and flechettes are the norm. Other rounds has been fazed out as other systems are more effective.

Even for its non-existent recoil, the mechanism isn't fast enough to provide faster fire than one shot every 5 seconds or so. In the dark, the muzzle flash and the burning propelant will be a problem during night operations as the operator risks boing blinded after firing the weapon. Nightvision equipment may manage to reduce the flash, but it will in most cases make the situation worse as they take some time to get the vision parameters back inot normal levels effectively blinding the operator.

While this is a problem, it is regarded as a minor one when faced with amock robots. However, the weapon is used sparingly as other alternatives are sought.
