Ok, this creation was inspired by Total Annihilation, a RTS game I played as a small child. ( also, you'll find A LOT of my creations are video-game inspired. I guess you are what you do, or something. If I had enough specialized pieces, I guess I'd be building all the famous metal bands in concert, but I don't, so...)
An overview of the map. Red is on the left, Blue on the right, and the killing field in the middle. Early warning, the pic of no man's land is straight awful, which sucks because it's the best part.
A half-decent shot of Red base. From left to right: the vehicle and K-bot labs are in motion, building new engines of war. An Engineer is assisting the K-bot lab with its repair beam. A pair of newly formed units, one of which is a mobile missile launcher, roll to the front, as a radar installation does its radar-y thing, and an artillery piece lets it loose. In the back, a generator keeps the whole base powered with Energy, while a line of metal extractors churn to keep the base's Metal production going. Another Engineer is finishing up a metal extractor.
There's also a sweet SAM turret I made, but, of course, my past self was a moron and didn't picture it.
Oh, never mind. I did! Hey, one less retard-point in your favor, past self!
This pic hurts my very soul. If anyone has the balls to look at the blurry horror for more than 2.64 seconds, It's a pic of the different war machines trading fire across no-man's land. You know, the machines I spent hours making. That my past self had to go and crap on because he couldn't take a decent picture.

Anyway...
Last pic. The is the Blue base, obviously. From front(ish) to back: two construction K-bots work on some new structure (barely pictured). An Experimental Gantry build a huge new death machine. One to rule them all, and in the Darkness bind them. Blue's own artillery responds to Red's in kind, while Blue's vehicle lab makes another unit. In the back a pair of metal extractors is protected by an AA turret, next to a long line of Energy generators.
