Out Of Character (OOC)
It's occurred to me that you guys might not understand why I want the ranks I've asked for.
The idea is that this is unlike any war the US has fought since maybe the US Civil War in that it's been an existential threat from the beginning and the attritional nature of the combat has annihilated literal generations of combatants. As such the traditional rank advancement and rank balance that for generations has been an assumption simply does not apply, almost the entire force of the USA and other belligerents is comprised of very low ranks with a small cadre of higher rank survivors that don't feature here.
Now, I am going to need some NCOs and an officer (I don't subscribe to the theory that officers are superfluous, they just have a different job) but a vast array of mid rankers isn't needed. If everyone who signed up plays, and I seriously doubt it, then I'd need one 1st or 2nd Lieutenant, a low Sergeant and two Corporals. Corporals are a thing again as the NCO school disappeared two years ago.
