Too easy to deserve 50 points and a badge, yet way too simple (in terms of gameplay) to for fifty levels. A twenty level game with an easy and medium badge might be more sensible.
Still a nice game tho, so 4/5 ;)
An 'inspire' officer ability would temporarily increase your units stats, maybe for 10 or 15 seconds. There would have to be a timer of at least a minute on it though.
There should be more officer abilities. An 'iron command' ability lets you take total control of a unit for a short amount of time (including choosing targets), would be handy for getting crates and taking out specific enemies.
