Hi,
Here are a couple of sound files I've whipped up.
233 represents a multi-shot grenade semi-auto launcher firing such as the US XM25 and the Milkor MGL-140/USMC M-32.
234 can represent a US Mk-19/47 and other grenade launchers and slower firing auto cannon.
A couple of thoughts on semi-auto GLs as well...
Weapon Number 082 US OOB M25 20mm GL should be adjusted from 20mm to 25mm (no sure if this would really change the stats) the caliber was upped when the XM25 was split off from the OICWS project, as it was found the 20mm projectile lacked sufficient lethality.
Weapon Number 124 Obat52 South Africa 40mm MGL Mk.1
This weapon was designed for rapid semi-automatic fire (all 6 rounds in 3 seconds) so I would recommend adjusting the HE Kill to reflect a "burst" of perhaps 3 rounds.
Add the 40mm M-32 MGL to the USMC and possibly US Orbats.
The M-32 is a modified version of the MGL Mk.1 known commercially as the Milkor MG-140. As with the MGL Mk.1 the weapon is designed for rapid semi-auto fire, so I would recommend adjusting it's HE kill for a 3 round "burst" as well.

It is currently undergoing operational testing in Iraq with USMC forces.
It will likely be fielded with two new types of ammunition:
Martin Electronics's 40mm M433I "Hellhound" round which is claimed to have double the lethality of the standard 40mm HEDP round and a 12m kill radius! It can be fired out of any standard LV 40mm GLR such as the M-32/M203/HK-69.
Martin Electronics's M1060I - DRACO (Direct Range Air Consuming Ordnance) - 40mm LV multi-purpose thermobaric grenade (which of course is already in the game)
Martin also has a HV version of the Hellhound round, the M430I, for the MK-19/47 AGL.
So perhaps add Hellhound firing versions of the M-32, M203, Mk-19 and Mk-47 for 2008+ with enhanced HE Kill (maybe 6?) and possibly higher warhead size as well(?).
