Superseded in importance only by the Coalition Navy, the Coalition Army makes up the bulk of the Coalition’s planetside forces. About eleven billion strong, the Coalition Army easily outnumbers the entire populations of many galactic polities, but even it pales in comparison to the Conseil and United Technocracies’ militaries.
The Coalition Army finds its roots in the old United States Army. Like its Marine and Navy counterparts, Army doctrine has changed little over the centuries. There are some differences, however: Imperial America’s Army was focused on deterring Soviet invasion and fighting insurgencies in America’s colonies. The modern Coalition Army revolves around the doctrine of OrbitSurface Battle: the aggressive use of armored units to punch through enemy lines and orbital and airborne support to cut supplies feeding the enemy. This is more similar to the United States Army’s doctrine during the Great War. The Coalition Army's primary purpose, however, is holding onto planetary territory the Coalition desires. Otherwise, the Navy is ordered to simply bombard the enemy world until it requires terraforming to become habitable.
The Coalition Army, in stark contrast to their Conseil foes, focuses on fighting at a long range. This is reflected in their small arms, which appeal to the myth of the marksman, a myth that goes back to the American republic. The Army’s M98r sonnecoil is semiautomatic, but Army soldiers are taught to reject spray and pray. They are only to fire when they know they can hit the target, as a suppressive fire role belongs to the volley gunner. This practice is only to be broken in case of encirclement. Unlike the fanatical Conseil, Army units are taught to retreat and regroup if their squads suffer massive casualties, unless an officer orders them to hold their ground for a strategic purpose.
Typical Army squads are composed of six men. Four of these men are equipped with M98r sonnecoils and are the core of the squad. One man is armed with either the M42 light volley sonnecoil, or the M44 sonnecoil autorepeater (which has begun replacing the M98rs). The last man in the squad is either armed with an M2 ermanic charge launcher, fulfilling the anti-armor role. Army squads are meant to support one another, with one squad laying down fire while another closes in for an easier kill. Normally, every Army platoon has an assigned “point” squad, who are provided with heavier armor and minivolleys and sonnecasters in place of M98rs. These are also normally armed with ermanic demolition charges, in case a hardened enemy position is encountered. Point squads are also armed with incendiary weapons and single-shot flame pistols, used mostly to render enemy thermal optics useless. Point squads deviate from regular Coalition doctrine, being more similar to the Marines in that they prefer close range combat as their compatriots rain fire down on them. Although Army casualty rates are lower than their Marine counterparts, Army units are more likely to have heavy enemy fire directed at them, as by the time the Army touches down the enemy is normally alerted to the Coalition’s presence because of Marine strikes.
Outside of regular platoons are “support” platoons, mostly composed of dedicated volley gunners (armed with the heavier M50 volley gun, which fires .75 caliber rounds), ermanic mortar squads and Army engineers. The Army’s IFVs and light armor also fall under the responsibility of support platoons. Mortars are important to Coalition doctrine, as it discourages most enemies from advancing on the more vulnerable Coalition rifle squads. The Green Berets, the Army’s supersoldier program, are of their own division but usually lend a support role, acting in conjunction with the Marines to fight behind enemy lines.
The Army’s armored forces are undoubtedly the most important. All Army divisions are mechanized, but armored units follow a separate command than their infantry counterparts. Coalition armor is heavier, faster and packs a bigger punch than their Conseil counterparts, as they are intended to operate independently as opposed to being strictly infantry support. Armored units usually charge ahead of Coalition infantry, punching through enemy lines and harassing the enemy’s rear in conjunction with aerial and orbital support. Coalition armor is also used to clear out buildings with entrenched Conseil infantry and as mobile shields for Coalition infantry. Unlike Conseil armor, all Coalition vehicles are equipped with energy shields that could take at least five ermanic charges before shutting down. The Coalition’s heaviest vehicles, the so-called superheavy tanks, have been known to crush entire enemy battalions on their own and only go down with orbital fire, but are not very maneuverable.
