Well... I use a modified data set (of my own design)
I have a mount that increases the range of weapons for troops which means you can build em and have em shoot out into space and hit ships. To ballance this I have a negative hit modifier on em. Seems to work out pretty good.
Also they can still shoot out into space even without the mount... just the range is limited... though in MP I have found this usefull for stopping transport ships that want to drop troops down.
Sorta a preemptive defense... shoot em before they land.
