[MetalMilitia]

I've been playing it quite a bit recently. Lots of 2+ hour long skirmish games, which are really fun. Especially if you have a well defended front line so you can build up artillery, shell control points then move troops and engineers in to extend the front line.

One of my favourite units are the Axis' Walking stuka enhanced half-track. It unleashes a large and powerful rocket barrage which can hit fairly distant targets with a fairly reasonable spread.
Also the Axis' heavy flak cannon is insanely strong - really hard to take out if you are facing one due to it's extremely long range but if you have on one your side you can pretty much leave it alone and let it decimate any approaching units.

Overall, great game.
