Hello Ason, I currently am the Commander of the Military Force for the Rhynelands, in the Kingdom of Vornair. I can answer for myself and my men, and to that point relating to yours, to become a Sergeant or a Lieutenant is purely based off of Merit. Having a package greater or equal to "Elyrian" does not matter to us, what matters is your capability to perform your duty. I would hope that other militaries or factions hold that regard as well. Also, I agree, we haven't seen much discussion on the Military side of things thus far, however we are hopeful that will lighten up.
If you have any questions about the Military in CoE as we know it right now, I would be happy to answer them for you, to the best of my capability.
