Star Trek: Away Team

In Level 12, the one on Romulus where you plant four anti-matter charges, there is a computer terminal in the north and one in the south. If you have someone use their "computer skill" on both of them, it will open up the explosive sniper round line of study. I don't think this is crew member specific, but I used Ivan Verov. The explosive sniper round will take down targets close to the primary target.
