Of course we need to talk about problems, im not very invested nor do i know much about the situation, i did however see this video : https://m.youtube.com/watch?v=J9niN4jiRig where the desertion problem was discussed. @ 12:10 -ish into the video. Basically what is said is that there is a problem where they cant choose what unit they sign up to but if they desert and then come back within a couple of days they can enlist again and choose their prefered unit, dont know if its true but that is also a take on the situation.
