So, I just got a few of my soldiers in Enemy Within up to Colonel Rank, and another soldier up to Captain so I decided I was going to make them into MEC Troopers to balance out with my Psionics. However, it won't let me. When I go to select them for the augmenting process their names are grayed out. But I can modify their genes if I want to, though I haven't yet on either of them.
Some help would be greatly appreciated.

You need the following to make a MEC Trooper:
If the soldiers in question are Colonel/Captain, not psionic, and have no genetic modifications, then it should work (assuming you have the cash and the meld).
Note that initially the soldier also needed to not be wounded, but this requirement was removed in a patch a couple years after launch and does not apply if you're up to date.
