I'm wondering just
how sensitive the imagers are in terms of temperature gradients. Could they detect the heat-signature left by human
footsteps (assuming movement at a walking pace) against the background thermal radiation?

My bro uses that on operations.
I've tried persuading him to wangle a thermal imager he attaches to his sights for me to play with but no dice. THose things are sewn up tight into
the army stores network. They are 100% accountable and the searches the RMPs do nowadays to check soldiers returning from Operations are very very
thorough.
