Re: What is T-UGS?

A Tactical Unattended Ground Sensor or T-UGS is a deployable motion sensor. It collects seismic, acoustic, radiological, and electro-optic data to track any movement in its range. The T-UGS can track, classify, and identify any target within its range and relay it to across the network in almost real time to a platoon size element of soldiers as an early warning device.

But it is from BF3 so maybe you can complete the challenge in Portal mode?
