These rapid fire guns are the norm for the Colonial Marines during their missions. The occasion is rare when a Marine does not carry one of these into battle. This gun is rapid fire and holds 99 M309 rounds per magazine. It becomes very easy to run out of ammunition when using these. Also incorporated into this weapon is a PN 30-mm hand pump grenade launcher, which almost always is armed with M40 High Explosive fragmentation rounds, which have an effective range of 400 meters.

The Pattern Ballistic Armour includes a defensive blast helmet and armoured vest. The armor consists of an outer layer of ultra-light titanium aluminide alloy, a middle layer of boron carbide resin and an inner layer of woven kevlar fibre. It's effective against low calibre and non-armour piercing rounds but is vulnerable to high calibre and armour piercing ammunition.
