Here was one advantage of soft ammo. The two techs would be out for maybe an hour, but nothing about them gave any obvious evidence as to what had happened. No damage to clothes, no apparent signs of injury. Nothing that would necessarily instigate a full-scale security alert. The pair could have passed out drunk. Inside this power and water hub, they could conceivably have contacted some toxic substance or even high-voltage electric and been accidentally stunned or knocked unconscious. Whoever found the fallen techs would probably take a long, hard look at the surrounding pipes and equipment for signs of some technical malfunction. That was good because it would waste time, and one man's loss was another man's gain.
