On my first and so far only attempt at just killing the principal terrorist wing mission target then leaving, he was dead 1 minute and 40 seconds after my first trigger press. Obviously that could be reduced with practice and outfitting. It's much quicker just to wreck'n'run than to take on the whole wing.
Unfortunately as the mission rewards are the same for solo-ing a wing mission as for doing a regular assassination mission, there isn't really any incentive to do it at all except for the welcome personal PvE challenge.
Wow, that seems quick.
What are you using?
