Very nice, but what I noticed while playing:
If you build a trooper in the baracks (sp?) its counting up to 100 which is normal, but although it has reached 100 for quite a long time, no trooper apears.
This only happens if you have already produced some troopers.
(and no I did have resources like 7 water, 1000 oil and over 200 metal-stuff)

Another thing which would be nice to implement:
If you have multiple units selected (like: 5 troopers) and send them to a location, they are running "into" each other while trying to reach the target.
So a "formation" or "group" movement would be handy for thoses situations.
