Just had to relay this short spell from my recent game.
I'm playing a cluster map with the goal of taking all the planets in my cluster only, so am rushing up the col. techs. Have found an Ice planet on the edge of my cluster with the Troop bonus (Fortress of Toorak iirc) which is also close to my Naxillian friends, so I set a destroyer to guard it while getting the tech to colonise it.
As I'm not at war with the Nax, I babysit the planet; sure enough a Nax colonyship turns up which I dispatch unceremoniously.
At 90% Ice Colonisation Tech another Nax col.ship appears; but before I can order my Destroyer to attack it, I notice its 'escaping Destroyer xxx', despite the fact that we aren't at war. Apparently my destroyer has a rep.
So I get Ice Col. Tech and send a Boskaran Col. Ship to what will become a producer of the most bloodthirsty ground troops the universe has seen, and I think in pre-RotS terms 'do I want to ferry these super-troopers to all my planets as would be the smart, but super-tedious move' then I realise I have the clone troop facility tech.
Now I get it, every planet gets a troop cloner, except the super troop planet which gets a Troop Academy, I turn off auto Troop builder, delete my crappy troops, produce one awsome troop, turn the troop builder AI back on and voila; all my planets are building mad troops.
Small things that make me happy about buying this game
