==Hua Yuan Armored Siege Regiments==
The birth of the Hua Yuan Armored Division was entirely by accident. A less-than-competent member of the Administratum assigned all of Hua Yuan's heavy armor to them, and as result they take being a tank regiment very seriously and are very professional in the greater imperium sense. No flashy colours, no gang behaviour; they exude professionalism. They feel like the Imperium had set out to give them this task, despite it being entirely an accident. They are considered uppity for this but also they tend to survive due to it.

The 1st Hua Yuan Armoured and their successor regiments consists almost entirely of Leman Russ battle tank variants due to their origins, but since proving themselves and their adopted doctrine have implemented Basilisks and their variants into service as well as Bombards, Colossi, Ragnarok and Thunderer Siege Tanks. However in more recent engagements the Armoured Regiments have utilized Deathstrike Launchers and Manticores as well as Hades Breaching Drills to great effect during Hivecracking engagements. 

"Hivecracking" is a form of siege warfare utilized by most armoured Hua Yuanese regiments. The optimal Hivecracking tactics are to encircle the hive in question and advance, utilizing fixed gun emplacements, mobile artillery, and armoured elements. Typically fixed artillery, either provided by the host planet, another Regiment, or by the sparse few artillery companies some Siege regiments have, and is used to highlight strategic weak points and draw fire from the advancing mechanized elements.

The tanks and other wheeled and tracked assets usually harry defensive positions and attempt to create breaches to be utilized by Exterminators waiting in reserve. Destruction is often extremely precise and thoroughly calculated, so as to not invalidate any maps and layouts of the hive. Typically six breaches will be attempted to be made, six on around the sides and one in the center, either through insertion in the top or through tunneling efforts made by the Exterminators, mimicking the horrific "Seventh Wall Fall" event in Hua Yuan's history. The Exterminators then perform a "Flash and Clear" on a theater wide scale, Companies rushing into the breaches at intervals, so the enemy can't fortify any one position, then rendezvous in predetermined locations or an auxiliary location. When fighting enemies such as Tyranids the Exterminators will usually choose to utilize only two flanking breaches so as not to spread their numbers thin.

The Armoured units stand in reserve and provide covering fire and will finish off enemies flushed out from the breach. Once the outer layers of the hive are secured they will usually close in, denying the enemy any escape and providing semi-permanent firebases or fully operational installations for allied force
