User blog comment:General patton 101/101st ghost regiment/@comment-25222488-20141011061313

and as for numbers im going off soon once i have accounted for 100,000 men and 9,000 vehicles im going off this wiki contributor that nicely gave me this info-

Other than the spelling and grammar, I'd say your biggest issue to resolve is seemingly a total mis-understanding of unit structure e.g.

A section/squad = 8-10 troops...a section officer/sergeant etc runs this (sometimes these form fire/combat teams of 4-5 troops each)

x3 sections = x1 troop....a troop commander runs this

x3 troops = company...which would normally have logistics (medical/air defence/coms), heavy/special weapons and a command troop (where the company commander etc sits) as additional units.

a given number of companies (5-7 ish) would form a regiment. 750-1000 ish troops

3-5 regiments would form a brigade 5000 ish troops

a few brigades would form a division 10000 ish troops

a few brigades form a corps etc 20000-30000 troops

So 40 million....would be massively excessive, it would maybe be a crusade but not a regiment or whatnot.

Germans in WW2 and thus alot of modern armed forms now have 'Battlegroups' which is just a development of the 'combined arms' units really. These are designed as a solution to a problem with a breaking of traditional unit structure to achieve a aim so might have extra air defence/offense abilty or be less/more mobile (armoured fighting vehicles/helicopters etc)...generally about regimental scale ish

Special forces will be ADDITIONAL ranks not wholescale deployments. White shield like units as you like Cadians would be likely ADDITIONAL ranks, not whole scale deployments too but I can't recall canon on that.

Some canon issues as well are that the Imperial Navy is not under the command of the Guard (Army) to prevent excessive control of power and mobile power at that, following the Horus Heresy.

Cadian's are from Cadia...not Galifrex....Galifrex could be a staging post planet, but they wouldn't stay there, they would assemble, train abit maybe then move to task.

15 years of non-operational, non-deployment training?...Not leaving long for people to actually fight (after taking account of time to become a adult...time to retire/age (aka still be able to fight).

Keep up the good work but don't get carried away, often good fiction is only like that as it's routed in some basic truths.
