Master of Ordnance - Regimental Variations: Because the role of Master of Ordnance is relatively formalised above the regimental level by the Departmento Munitorum, there tends to be little in the way of variation inhow different regiments actually utilise their capabilities. The procedures used to call in artillery fire support are by necessity standardised, and so little variation is possible. That said, the way different regiments train their Masters of Ordnance can differ, as can attitudes towards these specialists.The Death Korps regiments of Krieg have on occasion beenseen to demonstrate a particularly fatalistic attitude towards the procedure of calling in artillery fire support. The Death Korps place very little value on the life or well-being of any individual troopers, and this extends to the manner in which their Masters of Ordnance call in fire support. Most Masters of Ordnance ensure their comrades are well clear of the area to be targeted unless the destruction of a specific enemy is demonstrably more important than the lives of their friends. The Death Korps pay scant heed to the safety of their own troops, calling in overwhelmingly destructive fire missions at the expense of their comrades' lives. The Death Korps regard this as due penance and time after time have been seen to march stoically onto a battlefield churning with explosions.Certain regiments of the Catachan Jungle Fighters are noted for their occasionally antagonistic relationships with nearby artillery support regiments. Their frequent role as forward elements during combined arms operations means that the Catachans are often in the line of allied bombardments -- as was the case for the Catachan 223rd on Aeyras in the Spinward Front, when the order to bombard the jungle they were infiltrating came in with little warning. This islargely because the Catachans commonly operate in dense terrain where visibility is poor and where fire support missions must be called in with incredibly accurate detail. The Jungle Fighters trust few outsiders or higher-ups to call in fire support for them and soprefer to do so themselves. Unlike the selfless and self-sacrificing Death Korps, the Catachans believe that the Emperor is usually best served by their continued survival, and thus prefer it to be their immediate comrades who are calling down hundreds of pounds of high explosive within such close ranges rather than far-away officers uninterested in the collateral damage.Many regiments of the Elysian Drop Troops make extensive use of large-scale fire support, in their particular case often delivered by the warships of the Imperial Navy. This is because the Elysians specialise in planetfall missions and it is rare for there to be any unit already on the ground capable of providing the overwhelming firepower needed to soften up the enemy ahead of a mass drop. In addition, the Elysian regiments rarely carry any type of heavy weapon nor field any vehicle larger than a Sentinel, and must therefore rely on external formations to provide any heavy support. Needless tosay, the Drop Troopers have become masters of intricately preplanned artillery strikes designed to reduce enemy positions to rubble and, most importantly, force him to keep his head down while the Drop Troopers are engaged in the part of their attack where they are most vulnerable -- the drop itself.Cadian Shock Trooper regiments make extensive use of Masters of Ordnance. So militarised is the Fortress World of Cadia, and so dedicated to all forms of warfare are its regiments, that almost every type of unit possible is represented amongst its forces. There exists an almost unique relationship between the different Cadian regiments, the officers of many regiments having trained together or served together in the Cadian Youth Army before being tithed into the Imperial Guard. Because there are so many Cadian regiments in Imperial service, it is not unusual for entire armies to be made up of units from that same world, and for there to exist an especially close relationship between commanders. These ties simplify the process of mutual support enormously, making Cadian forces far more effective than their sum of their parts.
