Spinward Front - Imperial Forces Present on Kulth: Lord General Ghanzorik’s forces represent the greatest operational concentration of the Imperium’s military resources in the entire Calixis Sector, but still they are insufficient to strike the decisive blow that will take the world once and for all. At the last estimate, they numbered at least five million troops, around two thirds serving in front line combat units and the remainder committed to second line reserve and support formations. In addition to these, countless more are engaged in the ceaseless logistical duties by which such a large force is maintained. Regiments are drawn from all over the Calixis Sector and every world able to raise a tithe is represented in Ghanzorik’s armies. With the events surrounding the recent rise of the daemon known as the Dei-Phage who was mistakenly believed to be the resurrection of Saint Drusus, numerous regiments have been drafted in from sectors much further afield, at least in part to ensure their loyalty cannot be called into question. These include regiments from Cadia, Tallarn, Vostroya and many other famed Imperial Guard homeworlds. Rather than being raised specifically for the war on Kulth, these regiments have been drawn from Segmentum Obscurus reserves or re-tasked and diverted from whatever operations they were initially raised to undertake. Some are long-service veterans with more than a decade of experience at the front line, but they will be bitterly disappointed if they expect to be assigned to fight a battle from which victory might derive settlement rights. The war on Kulth is expected to grind on for decades to come.Amongst the Imperium’s forces on Kulth can be found every type and variation of fighting force. The Imperial Guard is an incredibly varied organisation and so even the main line infantry regiments range from small bodies of heavily-armed-and-armoured Grenadiers to massive formations equipped only with the crudest mass-produced weaponry. Supporting these infantry forces are artillery regiments fielding every imaginable form of heavy gun from massed mortars to super-heavyself-propelled artillery. Leading the infantry in their massed assaults are the tank companies, most equipped with the ubiquitous workhorse of Imperial Guard armoured forces -- the venerable Leman Russ main battle tank. Others go to war in the fearsome Baneblade or one of its variants, eachso heavily armed it can slaughter hundreds of foes or even strike down the lumbering Gargants the Orks use as their version of Imperial Titans.Mechanised infantry regiments ride to war in Chimera armoured personnel carriers, while numerous other regiments utilise all manner of riding beasts in the mode of classic mounted cavalry. A small number of regiments operate as Drop Troopers, and “Old Steel and Blood” is fortunate to have a corps of Elysian regiments at his disposal, for these are amongst the finest exponents of aerial and orbital assault in the entire Imperial Guard.The majority of these forces are stationed at Fort Drusus, or at least mustered there before being assigned to one of the numerous front lines stretching across millions of kilometres of Kulth’s surface. Fort Drusus is a sprawling base the sizeof a city, its landing fields never silent as millions of tonnes of materiel are shipped in each and every day along with fresh meat for the front lines. Newly drafted regiments are lucky to be granted more than a day to acclimatise to Kulth’s atmosphere, which most note tastes like ash and smells of ballistic propellant -- a sensation they soon grow used to if they live long enough. Having marched or ridden out of Fort Drusus’s mighty Aquila Gate, few ever return alive unless their regiment has suffered such a mauling it is forced to withdraw for reconstitution. Most only make the return journey through the Aquila Gate in a Munitorum body-bag, having given their all for the God-Emperor of Mankind.
