I may have been working on some back ground fluff to my
Astra Militarum Imperial Guard army, actually a Techguard force of the Adeptus Mechanicus. I recently attempted to build them in the Only War regiment creation rule-set and the need to more fluff followed.
Here it is if you wish to peruse. Please feel from to message me with thoughts and questions!
The Phi Delta 100101 are a regiment based from the world Schindelgheist, an Adeptus Mechanicus labour-forge powered by the offenders from other forge worlds. Such is the population and birth rate that each generation of colonials is recruited into the Phi Delta 100101 Techguard Legion, supplementing the constant attrition of warfare amongst the penal legionnaires. This constant removal of population allows new shipments of criminals against the Omnissiah to be thrown into the forge’s meat grinder and gives the genepool of Schindelgheist a constant new influx.
The Phi Delta 100101 are by Techguard standards rather unorthodox, operating as a scout and Light Infantry regiment they utilise very few vehicles aside from Sentinel walkers and several air support units. Instead they rely on a very high number of flesh units and crew support weapons heavily augmented with Omnissian-gifts to bring the fight to the enemy. Many of the more criminally minded recruits are partially lobotomised on conscription and their higher though processes replaced by complex doctrina-wafers and noospheric control relays. Many trooper-legionnaires particularly those in marksman dedicated squads enhance their gunplay with optical links to their weapons, direct datafeeds from the guns sights through eye sockets.
While the Phi Delta 100101 is a single regiment it’s true size is unknown, much in the same way the Vostroyan First-born are broken up into hundreds of battalion sized units each with its own service history and standard, so too does the Phi Delta 100101 have many component units. Some specialise more in stealth or reconnaissance, sharpshooting, support or over whelming firepower. The Adeptus Mechanicus refer to these units as maniples and treat each as its own separate combat unit, with its own traditions and nicknames.
Commanders for the Phi Delta 100101 are taken from Secutor training academies all over the Imperium, meaning that no “home grown” commanders are used and no planetary loyalty exists amongst command staff. Occasionally a member of Schindelgheist’s manufacturing overseer class accompanies the Phi Delta 100101 into battle escorted by a unit of fully trained and enhanced warriors, most often this is to test some newly restored artefact or piece or archeotech. Even senior NCO positions are filled offworld and any infraction of discipline is immediately dispensed with. The Trooper-Legionaries of the Phi Delta 100101 are essentially petty criminals compared to other offenders dealt with by the Adeptus Mechanicus. More extreme heretics are turned into the berserker warriors known as Archo-flagellants and are used on occasion by the Phi Delta 100101 shock battalions as line breakers, either for drawing fire or by tearing through defensive positions.
Traditionally each battalion uses autorifles rather than a las-based equivalent as the machining for higher grade focussing parts and capacitor chambers is normally limited to heavier weaponry. The solid round weapons, such as autorifles, grenade launchers, mortars and autocannon, favoured by the Phi Delta 100101 are more commonly used by the underclasses of Schindelgheist, and are actually one of the main exports of that world. Favouritism for such weapons carries over into the recruits drafted. Hard rounds and grenades are smuggled out of Manufactorum-cathederals and used as bartering tools all over the world.
Even with a Light-Infantry specialty there remains a need in any regiment for a heavy infantry element. In the Phi Delta 100101 this role is filled with the use of heavily augmented vat grown servitors, similar in size to the ab-human Ogryn warriors, the servitors have heavy shot-cannon and rapid fire ballistic weapons grafted onto their arms and ablative flak armour plating bolted to their skeletons. Trained to keep up with the forward scout elements of any Battalion within the Phi Delta 100101, used as walking shields for the regular troopers in the same way other Regiments used APC’s once dismounted.
