Millatary: Depends on what faction

Orks: No real millartary sturcture, just level of the settlment, maybe some buildings for the more elite troops (Like Say Black ork armoury would train black orks)
Empire: Should be simular to the normal one in MTW2 Sort of like Like
Militia Qauters --} State Barracks --} ETC
Bretonnia: Simular, but based on class rather than troop type so...

Stables --> Knights Stable --> ETC
Peasent Quater --> Millitia Quaters --> Chamber millitant ETC (Only improves armour/rank rather than troops avalible)

Choas: Mainly depends on settlement level, but perhaps some defferences depending on temple (Like khrone shrine would train khorngors, then a temple of khrone would train Chosen)

Elfs (All kinds): Same as empire to a extent

Lizard men: Level of settlement

Dwarfs: Simular to empire

Choas dwarfs (If they are in):

Forgery --> Large forgery ---> Industrial Forgery ---> Grand Forgery ----> Supreme forgery
Maybe one for monster (Ones you should put in would be Gnoblars, orges, minotaurs possibly Black orks (there mentioned in fluff of that might have been bred for construction perposes)
