Sam Fisher- Anti-Heat Tracking

Sa­rah car­ried a tri-ro­tor drone in her kit, a com­pact micro-UAV that could be hand-de­ployed in the field to give op­er­a­tives their own aer­i­al re­con ca­pa­bil­i­ty; but what was fly­ing around the vil­la did not be­long to Fourth Eche­lon. “Wait, I see it. Quadcopter, your six o’clock. Looks like it’s be­ing man­u­al­ly operated, like­ly by Kobin’s se­cu­ri­ty.”

Fish­er weighed his op­tions. The 4E tac­ti­cal suit’s stealth capabilities might be enough to hide him, but if Kobin’s drone had thermographic, heat-read­ing vi­sion, the op­er­a­tor would be able to pick out the un­con­scious guard ly­ing hid­den in the grass.
