The whole point of the last game was to do missions to get money to increase the size of your army. With an army cap, that makes it harder to capture anything starting out. 3/5 not bad, but you made a few mistakes not present in the first one
I like your exp premise, but you need to fix something, true a srg would be very skilled compared to a fresh recruit, but a fresh recruit wouldn't stare dumbly as the enemy marched on his position, nor would he miss at point blank range more often then not.
