GL-06

The Brugger & Thomet GL-06 is a single shot grenade launcher featured in Call of Duty: Iron Wolf.

Multiplayer
"The GL-06 fires one grenade to arc across long distances. It will destroy anything that is directly impacted or a near-hit. Beware the frequent and long reloads, as it leaves you open to attack."

- In-game description The GL-06 is unlocked at level 17, behaving very similar to previous single shot grenade launchers in the past like the M320 and Kastet. Aim is very critical because a player wielding this weapon is most vulnerable when they have appeared, fired and missed, leaving them exposed to a counter attack.

The weapon has a very low rate of fire, making Sleight of Hand a very good option to quickly execute reloads. Damage is very high of the grenade launchers, slightly superior to the XM25, but trades capacity for damage. A grenade landing directly impacting or very close will always result in an instant kill. An enemy with Blast Shield will survive an explosion very close, although they will be significantly wounded. They are only lethal to Blast Shield users if it is a direct impact.

Like all grenade launchers, it arcs downwards the further it is shot, therefore many players have to aim above their enemy to score a kill.

Zombies
The GL-06 is possible to be obtained in Zombies from the Mystery Box, costing 950 points. It has a slow reload, low rate of fire and most of the time is unable to kill zombies. Due to these traits, it is often an unfavorable weapon.
