Editing Hua Yuan Exterminators (section)

===Exterminator Combat Doctrine===
All Hua Yuan regiments have developed their own unique doctrines, and the elite Exterminators are no exception. Relying on quick reaction times and swift operational tempos, the Exterminators offer an effective if seemingly frantic and chaotic fighting style, both in combat engagements and at the command level.

====FOBs and Firebases====
An integral part of Exterminator doctrine is the use of forward operating bases (FOBs) to maintain forward momentum when clearing out a Hive. During the initial penetration of a hive and the ensuing firefights, numerous hab-blocks will be leveled as part of collateral. This freshly created real estate is the perfect environment to set up a firebase, moving light armor and light artillery into position to secure a solid point of entry and exit that the Exterminators can operate out of. Whatever the Exterminator’s preference, however, an FOB can be anything, anywhere: a tunnel system, a rooftop, a corner candy store, just reinforce it a bit, set up patrols, and move in the equipment and you're set. Normally a Hive can't allow for a legitimate firebases in their current state, so it takes some “renovations” in order to have a fully functioning one, leading to numerous complaints from men all along the administrative ladder. The hive would be divided into stratum accordingly, removing citizens and setting up firebases that they can perform quick, surgical strikes from until an area is deemed pacified. Repeat process until the entire hive is cleansed of the Imperium’s enemies. The Exterminators are quick to set up a network of bases, the rear ones concentrated around the points of entry are for command, infirmaries, supply and respite. The forward bases get setup in preparation for the next push or in pacified areas to bring supply lines forward.

The kind of operations performed out of the FOBs can be categorized in two: The Scythe and the Scalpel. When they set up a scythe, they are meant to sweep through a particular area, going block to block in the hopes of completely eliminating any enemy presence in their particular stratum. A scalpel is used when intelligence suggests high enemy concentration within a particular area, and perform surgical strikes to either secure points for other units, cut off the enemy forces and isolate them, or outright eliminate an enemy enclave. In either scenario, the operations rely on fast, heavy handed and carefully articulated plans to maximize surprise and confusion in the enemy ranks. They won’t occupy an operating base for too long, as holding a line can cause the theater to stagnate, and when Exterminators stagnate and lose momentum they begin to lose control of the AO. They like an AO to be just as chaotic as they need it to be, in ways they can manipulate. That or they want it nice and calm, or draw the enemy's attentions so they can surprise them, but a violent gridlock or a stagnating line is the last thing they want. The Line Infantry is virtually shit. They try to constantly be on the move in a strategic sense, constantly moving throughout a hive, setting up temporary bases in order to make sure nothing falls through the cracks as they progress. 

To that end, FOBs will be nothing more than staging areas with a communications company attached, parking spaces for supply transport units, and a lightly fortified command trailer. Everything will be made to be compacted down and moved ahead quickly to remain at pace with the troops advance. Medical units may be attached to these command elements, but are also forced to remain mobile, likely field surgery units set up to operate out Samaritans. Supply units follow immediately behind advancing troops, ready to prepare the next command/operations base as the AO is secured. In prolonged engagements,however, these firebases can be so ingrained and well fortified that they become permanent fixtures for enforcers and pdf’s once the Exterminators pull out and conflict ends.
