Ah, so you gotta get close in. :shrug: I've only ever successfully gotten troops into town once, and that was just yesterday, so I'm a newb on the whole troops and troop carrier thing. Normally I'm buzzing around overhead being flakkerbait.
I think it would be cool to change the distance, though, maybe make it quite a bit further out that they could be released and they'd head off in the "right direction." Would be fun to see, a few hundred troops running across open ground... oh the carnage that would ensue!
