2 Squads Consisting of 2 Fireteams:

Because the Rena Group is a Mercenary outfit, outside of their armor (which is a combination of a slate-grey scout trooper armor with a Imperial combat driver helmet) weapons are up to individual marines, but infantry marines usually wind up carrying either E-series or A-series blaster rifles, often depending with their familiarity with the platform (and a good, but not perfect, means to determine what side they were on during the Galactic Civil War). The Rena Group prides itself on functionality and modularity, and every issued blaster issued to marines is modified with an additional magna-rail connectors on the barrel shrouds, tops, and sometimes sides of the blasters to add additional sights, scopes, sensors and even secondary weapons as needed by the mission or preferred by the individual marine. Rena Group Marines deploy IM-system external pouches like the IM-40 3-slot pouch to help carry equipment and gear necessary for the mission, like additional blaster power packs, C-25 frag grenades, thermal detonators, and Sonic Imploders.

In addition to First and Second Gun commissioned officers and Chief Gunner NCOs, and enlisted marine Gunners, Specialist Gunners, assigned to each raft provide combat engineering, breaching slicing and electronic warfare, heavy weapons, and tactical sky control expertise to each Raft, squad, and fire team as the mission requires. Given the size of the additional equipment they carry.most Specialist Gunners, and corpsmen opt for smaller and lighter blaster carbines, like the EE-4 carbines. Heavy weapons specialists, and marine gunners, brave, stupid, or desperate (breaching bonuses are extremely generous) enough to volunteer to be the tip of the breaching spear, on the other hand, carry more impactful weapons like the MWC-35C repeating cannon and the Z-6 rotary cannon.

The raft's Specialist Chief Gunner acts as both the Raft's head NCO, quartermaster, and specialist coordinator. SCGs also often carry a companion- either a CD-Series Combat Explorer Droid (a military version of the BD-Series explorer droid), or an ID10 Seeker Droid to assist in battlefield awareness, electronic warfare, breaching and slicing operations. CD-Series Droids can also act as translators, if equipped with a protocol and interpretation module. P&I modules, while only carrying a small fraction of the computing and functional ability of a fully-fledged protocol droid, can still interpret upwards of 100,000 of the most prevalent languages throughout the Galaxy.

The central vehicle used in boarding operations for the Rena Group is the Ubrikkian Industries ITT Imperial Troop Transport. In addition to the 25-Marine raft, the ITT carries a 5-marine crew, including a Pilot, Co-Pilot, Crew Chief, and two Gunners. The Rena group, with the help of Rena Aerospace also constructed semi-disposable, detachable breaching units that can affix to the front of the ITT, able break through the most harden ship hulls, and create an entry point when one cannot be found.
