laser. Both solutions would probably require a tripod mount to avoid operator-sensor interaction. Advantages of the radar solution include its ability to penetrate clothing and perhaps armor. The laser can detect small, repetitive motion consistent with respiration. While a technological solution seems viable, given the absence of a specific program or deployed product, this mission area receives a yellow assessment.

Gaps in Force Protection Sensor Technology

Table G-4 assesses the gaps in force protection sensors. As in the preceding section, squad-level constraints—specifically, SWAP, mobility, CONOPS, and ease of deployment—dictate a more pessimistic assessment of the currently available technology.
