[@LordOfTheNight] I see almost nothing of military doctrine in there, and culture I was mainly just looking for naming, how officers would be commissioned, is it based off education/experience(field commissions) alone, or are other means such as royalty. 

Doctrine wise, I was wondering about how individual units would cohere to each other so I'm looking to create a sapper/engineer of some kind, and of course a lower ranking officer. So if we are going from a british stand point, I'd either be under artillery or the naval marines (weird reasons). Besides that, would sections be split up like in the british/most allied armies, like artillery (mortars/machine gun teams, artillery, anti aircraft emplacements, spotters), logistics (engineers, drivers, yeoman, etc), infantry (infantry and sharpshooters), cavalry (cavalry, armored cars, tanks, some planes[another odd thing to talk about during first world war british military]) or more like the german/italian doctrine, of if you think about it you can get it, so cav (anything mobile or flying), infantry (anything that is slow, and on the ground and not logistical), artillery and logistics (pretty much anything that isn't left with heavy artillery added in)
