Polish GROM [RHS]


Special Operation Forces Faction mod [SFF] that adds the Polish GROM- Also known as 'Thunder' and 'Silent Unseen' GROM are one of Poland's Special Operation Forces units.

Note this version is dependant on RHS Escalation. If you would prefer different dependancies there is a SMA version also available. They are not compatible with each other and cannot be enabled at the same time.

Historical Info
The Polish GW GROM ( Grupa Reagowania Operacyjno-Manewrowego) are Poland's most elite Special Forces unit, and were founded in 1990, and trained by US Delta Force, US Navy SEAL Teams, and the British Special Air Service. Named after Poland's WW2 special forces unit, the 'Silent Unseen' and have since garnered a reputation, even among other international Special Forces Units as being one of the best units in the world.
Motto- "Siła i Honor Tobie Ojczyzno! (Strength and Honor For you, Fatherland!) "

The Faction
The Polish GROM in this mod are accurate to a 2011-2016 timeframe, based on real life photographs and sources where possible, with weapons and equipment based on what they used at that time.

The Heckler & Koch HK416 forms their primary rifle, usually with a CQC 10 inch barrel. The HK416 14.5 serves as their Marksman rifle, using match grade Mk262 ammo, a bipod and a longer range optic. GROM grenadiers carry a standalone M320 GLM launcher to not weigh down their primary rifle if they are engaged in close range or urban fighting. The M249 SAW is their main autorifleman weapon and the standard sidearm is a Glock 17.

They have considerable on a squad level compared to other SF units as they carry M72 LAW launchers, which can be used in both anti-structure and anti-armor roles. They wear Multicam uniforms and OD/ Tan equipment, and a cosiderable number of their weapons have been spray-camo'ed in the field, which I have seen in photographs of GROM in Afghanistan.

Specialist Elements
The GROM have a dedicated Sniper-Spotter team, wearing a ghille suit with ATACS-AU underclothes, giving them precision supporting fire, recon or for HVT assassination.

A Breacher team, based on photos from a 2015 urban warfare exercise, is also in the faction. They are wearing OD base uniforms with Multicam body armor/ Opscores. Armament is all compact CQC HK416's with with Eotech red dots, and one member of the breaching unit can carry a M320 underslung or a standalone launcher. They speak a mix of English and Polish using the Contact radio protocol.

The GW GROM lack the heavier air assets of other SF units, instead having a light MH-6M Littlebird for transport or insertions, and having the Oshkosh M-ATV for vehicle support, with a mounted M2 50. Cal. Light Strike Vehicles in both armed and unarmed versions as well as Quads can be used for mobility.
They have a light Zodiac craft for water-bourne operations.

Faction has full Editor, Zeus, Task Force Radio and ALiVE support (faction name GM ) Also supports ACE3 Medical system.
