Replaces the firing sounds of some grenade launchers with those from Call of Duty games as follows:

1. "Arbiter" - XM25 from Modern Warfare 3 (also includes reloading sounds)
2. "China Puff 40mm" - China Lake from Black Ops 1
3. "Little Friend" - M203 from Call of Duty 4
4. "GL40" - Thumper from Modern Warfare 2
5. "KETCHNOV Byk-1" - GP25 from Call of Duty 4
6. "Piglet" - MK32 from Ghosts

These are all in the same soundbank, but a lot of the reloading sounds are in regular_weapon_sfx instead and are impossible to change outside of complete soundbank overhaul. Because of training.
