civilians and arbites

strategic points, your men are weak and inaccurate. The more powerful units are capped to help with balance. The civie_hq generates the main requisition and power supply, turrets add a small amount also. Building more hqs and building them in your allies starting zones will help you to consolidate your position. The chimeras and rusted leman russes can make for good armoured columns which pack a good punch whilst your foot troops die in their droves to hold ground but there are always more of them. This mod also works with SoulStorm although it has only been tested this a few times, the only difference being that dead bodies remain glowing purple.
Here is a new race mod you might want to try! This is based on the indigenous civilians and planetary defence forces (pdf) of the w40k world. There is no army size cap, no buildings to consolidate
