OK, I did this Last night so have some current information.

I have a racial ground combat trait of 90% and am playing engineers (so no bonus). My small troop units mount the cockpit and life support, 1 ground cannon and the rest is armour.

I attacked a 4,800 pop homeworld that had an addtional 100 similarily configured troops on it.

First wave of mine was 350 troops which didn't do it, I then had to ship in another 300 troops over a period of about 9 turns to win.

I have changed settings to 3 ground combat turns per go but that frnakly worked in my favour.

All in all, it tool 650 troops and a year to take down the homeworld
