So far i've been pretty confused on the actual use of the Colonel but recently while playing around in sandbox, if spammed, it could make for a pretty mean fabber army. Just 7 or so can make a titan pretty fast. They also have tons of health. Of course, they cost a lot to make and to use. Is this what its meant for? an upgrade for the T2 fabricator? Ill have to try it in my next game and see what I can do with it lol.
