Scrap Balers go around the field converting scrap into little bales. These must be tugged back to base to be throw on a processing pile by a dedicated unit that does so automatically. An advanced scrap baler can drop bales with engines and guidance systems to attempt the trip on their own. The extractor form does the same as the mobile only without the need to pick up a set amount of loose to the internal tanks first.
Scrap Baler - Scavenger that forms dense scrap bales
Auto Scrap Baler - Extractor that piles up bales of scrap
Scrap Bale - Box that must be demolished by a constructor or processing plant
Scrap Baler Advanced - Scrap baler that drops advanced bales
Auto Scrap Baler Advanced - Auto scrap baler that drops advanced bales
Advanced Scrap Bale - Box with a basic guidance system and engine
Bale Truck - Truck that collects scrap bales and takes them to the processing plant
Other units and structures are as follows:
Bullpup Tank
EMP Device - Instead of a bomber, the Confederates have a large super conductor capacitor that can be used to temporarily boost effective firepower and defense of units and structures by slowly bleeding off its charge or shunt it into an enemy facility all at once to cause an overload.
Here are some images of the WIP Bullpup Tank:


This canister will probably find reuse on the turret, however that unit is designed.

Please feel free to give suggestions, make concept art, etc. Ideas that don't go into the confederates could go into another race. I figured I should just hunker down and stick to one race at a time though. Actually, the point of this topic was to get some suggestions.
