That's a Rad, and I'm not sure if it was recovered or created. Any way, it was an empty shell, not an active trion soldier.

Point is, if they drop bombs and explode, there are limited ways in which you can use them without blowing up your own city or defensive lines. But then again, in my opinion this is a secondary reason.
