That was very well written, kudos to the wikia contributor. You did not consider several very important factors, however.

They are going to eventually run out of ammo, and considering that some legions are range combat oriented the moment that happens, they are very much screwed. Because then the astartes are gonna have to use knives and it`s gonna turn brutal.

Some legions specialise in close range combat, they have more power weapons and mele weapons, when tha bullets stop flying, if they managed to stay in cover they will have the advantage.

Other legions specialise in hit and run tactics, if they manage to stay away from direct battle they could do serious damage, until the ammo runs out.

Legions specialising in deception tactics, or `spear head ones`, might manage to take out the leaders of other legions, crippling their command.

And my biggest question is: Are the primarchs involved in all that.
