when u followed the ingame tutorial then u'll be fine but just to make thing clear
1 u recruit nts by glicking on your colony and "recuit units" bubble
2 then click on the arrow
3 pick what ever you have avalible
4 wait a bit
5 and make squads when they are finished training
6 then when you have squad ready u'll see a ship on your colony
7 click on it and u'r mouse will turn into a target witch is followed with a slight curve
8 click on a outpost/colony yo want to conqer (Make sure u have more army than him)
9 and click Launch
10 then wait again and when the units arrive u'll get a battle report that tells who won
i suggest that you'd get a mentor from "Adopt a noob center" where you can go from the link at the bottom of this post
same goes with wiki, u can find pretty useful information there ...
if you have any questions more i'd be happy to answer those
