Total Imperial Guard Forces: 200 Million

Macarthan United Divisional Forces

With the death of the Emperor, and his continued fight in the Immaterium, some of the laws and rules that bound regiments of the Imperial Guard fell. The size of the Macarthan United Divisional Forces (UDF) is deceptive, since a large portion is not, in fact, the original regiment, but the splintered and fractured regiments that limped their way to Thresha Secondus, and the other planets within their control, and were absorbed into the regiment, their vessels absorbed into the standing Navy. The core Macarthan forces form the, quote unquote, elites of the new formation, while the absorbed regiments broadly fit into several divisions beneath the main banner. Having grown massively in size, the Macarthan have their original regimental cores, but have outer rings of regiments that now bear the same name as their own.

Macarthan Line Divisions (Regiments 2000th - 500th)
Organizational Structure: 5,000 Command and Control, 60,000 Standard Line Guardsman,10,000 Heavy Weapons Teams, 15,000 Veteran Guardsman, 5,000 Support Personnel, 5,000 Weapon Specialists (Grenade Launchers and Flamers)
Vehicles Per Regiment:150 Chimeras, 5 Malcador Assault Tanks, 5 Malcador Infernus Tanks

The Macarthan Line Divisions are the major backbone formed primarily out of men and women raised from Thresha Secondus, the surrounding planets under Macarthan control, and from the shattered and lost remains of various divisions that trickled their way to the Macarthan banner, and now serve under it, lacking a better set of options in many cases. The standard fare being Flak armor and bayoneted Lasguns, with frag and krak grenades, the standard troops are more than capable of holding the line. The heavy weapon teams carry heavy stubbers or missile launchers predominately. The armor seconded to the Line Divisions is fairly utiltiarian, a large number of Chimeras supporting the movement of infantry, while the Malcador and its Infernus variant provide armored support without reliance on the dedicated armor divisions.

Macarthan Recon Divisions (Regiments 499th -400th)
Organizational Structure: 5,000 Command and Control, 30,000 Standard Line Guardsmen, 5,000 Weapon Specialists (Grenade Launchers), 30,000 Recon Guardsmen, 10,000 Ratling Snipers, 5,000 Support Personnel, 5,000 Intelligence Specialists, 10,000 Veteran Guardsmen
Vehicles Per Regiment: 5,000 Motorbikes w/sidecars (Dedicated to Recon Guardsmen), 1,500 Tauros, 1,000 Tauros Venators

Unlike the Line Divisions, the Recon Divisions are lighter and faster moving over all, rather than being equipped to hold the defensive positions that the Line Divisions are trained and equipped for, the Recon Divisions act as the eyes and first response units of the Macarthan forces, capable of moving thousands of men and munitions with the dedicated Motorbikes, the ones within the Recon Divisions usually have heavy stubbers on the side cars, while the Tauros and its varient, the Venators, provide fast moving punches while the standard infantry catch up, including a large amount of Ratling Sniper teams, which replace the regular Guardsmen for sniper duty, leaving them free to operate in other capacities in the field of combat.

Macarthan Airborne Divisions (Regiments 399th - 300th)
Organizational Structure: 5,000 Command and Control, 55,000 Paratroop Guardsmen, 20,000 Veteran Paratroop Guardsmen, 10,000 Support Specialists, 5,000 Pilots, 5,000 Techpriests
Vehicles Per Regiment: 120 Vultures, 60 Valkyries, 60 Valkyrie Sky Talons, 60 Vendettas, 60 Drop Sentinals, 60 Tauros

The Airborne Divisions are considered, generally, the first men with boots on the ground at any situation or hotzone. Equipped with Grav-chutes, las carbines, and other specialist gear that an airborne division would require to operate, Veterans are often seen dropping with modified Krak grenades tied into bundles, for even larger punches against armor, and are dropped with the regulars, to provide guidance on the battlefield. Fielding the largest amount of

Macarthan Armored Divisions (Regiments 299th -200th)
Organizational Structure: 5,000 Command and Control, 30,000 Armored Fist Guardsmen, 10,000 Veteran Armored Fist Guardsmen, 5,000 Support Specialists, 10,000 Techpriests, 40,000 Tank Crew
Vehicles Per Regiment: 200 Gryphonne IV Pattern Chimeras, 30 Gorgon Transports, 30 Malcador Assault Tanks, 15 Malcador Infernus Tanks, 10 Malcador Defenders, 10 Malcador Tank Hunters, 3 Stormblades

What the Armored Divisions lack in infantry strength, they make up for in raw, armored power. Since the Macarthan's could never get a hold of Lemen Russ Battle Tanks, they made do with surplus Malcador Assault Tanks, including variants acquired and built on the fly as needed. While slower and more cumbersome than its lighter, modern cousin, the Malcador retains the raw firepower and is more durable, and its variants inherit these traits, making the Armored Divisions slower to deploy and arrive on the scene of the war, but once they do, all hell will be broken loose. The Chimeras are a special pattern that fields Autocannons in their turrets, providing better firepower for the Veteran Armored Fist Guardsmen that ride within, while regular Armored Fist are relegated to Gorgons, for making the initial assault during the breakthrough actions against enemy positions and forces. To lay the final blow, Stormblades were found and made operational, and now are seen across the fronts the Armored Divisions deploy to, providing command vehicles for the most veteran, skilled crew and commanders.

Macarthan Engineering and Support Divisions (Regiments 199th - 100th)
5,000 Command and Control, 20,000 Line Guardsmen, 40,000 Combat Engineers, 20,000 Veteran Engineers, 5,000 Support Specialists, 5,000 Techpriests, 5,000 Vehicle Crew
Vehicles per Regiment: 100 Trojan Utility Vehicles, 50 Atlas Recovery Vehicles, 40 Hydra Flak Tanks, 5 Hades Breaching Drills

Not all battles can be won in rapid, mobile affairs, nor do they go unscathed. When the time for recovery comes of damaged and lost vehicles, and looting the parts off enemy equipment, or when the trenches need built, or a plan hatched to break enemy siege lines, the Engineering and Support Divisions are tasked with figuring out the logistics. From well planned and laid out trench lines, plotting paths for the Hades Drills, to setting up the Anti air networks their divisions are responsible for maintaining, the Line Guardsmen are there to defend the Hydras and other vital equipment, while the Engineers are trained in close quarters assault, favoring shotguns and grenades of all sorts to follow up on breaks in enemy lines. Their motor pool is, barring the Hydra Flak tanks and Hades Drills, support and recovery vehicles used for recovering friendly and enemy wrecks, to strip for parts or restore to working conditions and sent into war once more.

Macarthan Artillery Divisions (Regiments 99th - 50th)
Organizational Structure: 5,000 Command and Control, 20,000 Heavy Weapons Teams, 35,000 Artillerymen, 10,000 Support Specialists, 10,000 Techpriests, 20,000 Line Guardsmen
Vehicles Per Regiment: 400 Heavy Mortars, 300 Thudd Guns, 100 Earthshaker Cannons, 50 Medusa Siege Guns

When a line needs broken, a siege needs lifted, or an enemy just needs completely, and utterly obliterated, the Artillery Regiments are given their fire orders and coordinates. Utilizing static emplacements moved into place by the Engineering divisions, the frightening number of heavy ordinance can be focused into a series of kill zones or, for a single division, capable of focusing every gun on a single sector, for the sole purpose of leveling any and everything that dared trespass against them. The Line Guardsmen assigned to these regiments are generally little more than for show, since if the enemy reaches the Artillery Divisions, things are far too lost for a handful of Guardsman, relatively speaking, to do much good.

Macathan Grenadier Divisions (Regiments 49th - 2nd)
Organizational Structure: 5,000 Command and Control, 50,000 Grenadiers, 15,000 Veteran Grenadiers, 10,000 Stormtroopers, 5,000 Support Specialists, 5,000 Techpriests, 10,000 Vehicle Crew
Vehicles Per Regiment: 200 Taurox APC's, 120 Gryphonne IV Pattern Chimeras, 30 Crassus Armored Transports, 30 Hydra Flak Tanks

When the Line Divisions fail, where the Armored Regiments can't ride and the Airborne can't fly, the Grenadier divisions go to fill the gap. With equipment, training, and favor second only to the 1st Regiment, the Grenadier Divisions are equipped with the best hellguns, hotshot lasguns, frag, krak, melta, and other equipment they might need for a job. Also given some of the most useful transports and dedicated Hydra anti air cover, the Grenadier divisions are not there to hold lines, their job is to break through and do the impossible, where the regular Guardsmen fail, the Grenadiers and Stormtroopers are tasked with succeeding. The strenuous training and strain on equipment limits their numbers, compared to the massive numbers of regular Guardsmen, but their effect is many times that of their numbers, so it balances out in the long run.

Macarthan 127th Lancers Regiment (1st Regiment)
Organizational Structure: General Alexander Sternfield, 39 Honor Guardsmen, 4,960 Command and Control, 55,000 Veteran Grenadiers, 20,000 Heavy Weapon Teams, 5,000 Support Specialists, 5,000 Techpriests, 10,000 Veteran Vehicle Crew
1st Regiment Motor Pool: 200 Gryphonne IV Chimeras, 120 Armored Sentinels, 40 Malcador Assault Tanks, 1 Stormlord

The original Regiment that gave birth to the New Macarthan sector of space, the most skilled, lucky, and talented men are recruited for service into the 127th, and put through the most difficult, and intensive, training and screening process to ensure the utmost loyalty to their commanding officer, the Regiment being personally led by General Sternfield to turn the tide of battle when the moment is most critical, when its no longer advantageous for the General to remain back in the command trench and direct the battle any longer. While his best and brightest Grenadiers ride Chimeras into battle, supported by veteran Malcador Assault Tanks, Sternfield chooses a unique entry into battle. He, and his personal retinue of the 39 most skilled men within all the New Macarthan Regiments, ride into battle on a Stormlord, utilizing its nature to annihilate infantry and light armor by the hundreds, while the Malcadors take care of what the Stormlord cannot.
