[Suicide Junkie]

Of the few times I got it to work, the result was poor since each time troops drop, a separate ground combat session is generated. Either I win after the first ship drops its troops or I lose with the first ship, the militia regenerates and I lose with the 2nd ship too. I have read about using troops in the first wave with only shields followed by the combat troops, but I have not been able to coordinate this with more than 1 troop ship.

This is an artifact of there being 10 ground combat rounds per turn. With so much shooting going on, it is usually over extremely quickly.

In my mod I set the # of ground combat rounds to One. That means your troops are almost guaranteed to survive for a while, and allows reinforcements to arrive from both races. When invading a large world, it can take a year or more, which I find much more realistic.
