The really interesting things to me are:
1) Invisible divisions, and the system to split units
2) Hiding top-tier equipment from the West -- even at the cost of not allowing their own soldiers to know what equipment they're supposed to ultimately use. Vs. the US, where soldiers are expected to be intimately familiar with their assigned weapons systems.
3) A really naive view of economics, that the military is "free" because the State provides it. It doesn't correctly assign the cost as that of the foregone alternative -- a tank means 100 fewer cars, etc.
4) "Role before Rank" promotions -- officers being promoted into a role above their rank as a precondition to attaining that rank. In the US system, that only really happens for certain General Officers; everyone else is promoted and then assigned, with most early to mid career promotions being either automatic or based on seniority and checkboxes.
