The fireforce was originally devised by the Rhodesian Security Forces during the Rhodesian Bush War in the 1970s. Like the Rhodesians, the U.S. Minutemen face indigenous insurgencies who are less well equipped, but can move swiftly over varied terrain. The fireforce is a vertical envelopment air assault using an entirely helicopter borne force, and it is very modular depending upon local conditions.
Most fireforces operate out of Minuteman firebases, which are heavily fortified airfields located in remote locations on frontier worlds. They react to enemy ambushes, attacks on settlements or observation post sightings, but they could also be called in by ground-based patrols who call in for reinforcements. The firebases commonly use OV-26G Cardinal forward observation tilt-rotors. The OV-26G is a variant of the base MV-26--it has more armor than the standard version, along with target marking pods, lasers for bomb/missile guidance, extra communication gear and a chin-mounted 7.62mm mini-gun. If enemy forces are spotted, the OV-26G will call in to the firebase and will remain on station to track and monitor the opposing forces. ARH-74D Omaha helicopters are also sometimes used for forward patrols.
A fireforce combat force is effectively a reinforced platoon of 6 squads. 3 squads are carried on board an MV-26D Dragonfly (the D-Car), which can land and deploy all its troops or once, or over a larger area. The 3 other squads are carried on board the three UH-60R Blackhawk helicopters (the G-Cars), which then often land on the edges of the combat zone to surround and flank the enemy. The fireforce commander flies on board the K-Car, which is an AV-26M Dauntless II that is armed with a 7.62mm mini-gun, 30mm canon and up to 10,000 pounds of missiles, bombs and rockets on external and internal weapons bays. Finally, riding Shotgun is a light attack aircraft, usually either an ARH-74D Omaha or AH-1Z SuperViper. The Omaha or Viper would usually initiate the assault, with the K-Car providing heavy fire support as the D-Car and G-Cars landed their soldiers. Landed soldiers would then use smoke grenades or flares to mark positions requiring heavy fire support from the Shotgun or the K-Car.
Fireforces have proven very effective in the Minutemen's counter-insurgency campaign over the years, particularly since the introduction of the AV-26M Dauntless gunship. It is a very modular and flexible formation, using any possible combination of Dragonflies and Blackhawks. Heavier assets like a CV-38 Grasshopper can also be used to bring in additional troops (up to 90) or even various types of armored vehicles--up to 3 M945 Mastiff General Purpose Vehicles or 1 Common Vehicle Combat System such as an M880 Coyote Infantry Combat Vehicle or M882 Badger Mobile Gun System. Heavier AV-38H Stunners or AC-130W Spectres can also be used to support fireforces (25mm five-barrel mini-gun, 40mm cannon and 105mm Howitzer each), along with heavier combat aircraft such as the A-17 Scimitar or FV-34 Matador. Seaborne fireforces have also been used, primarily operating off of Valley Forge-class amphibious assault ships on anti-piracy missions.
