This is a place holder post- I wanted to create the thread to remind myself about a special rule that I'm looking at for the Astra Militarum.
In the Codex, the Platoon Commander is an Elite choice rather than an HQ. This severely impacts the narrative. The Imperial Guard is the largest starting faction in the game, with a battalion in each settlement and a brigade in Aegis City.
It is absolutely unrealistic that there would be so many company level commanders, so we need a way to deal with rank. The easiest way to solve the problem is to just count Platoon Commanders as HQ units.
