The Unmanned Aerial Vehicle (UAV) Recon will reveal the position of enemies, displaying them as red dots on the minimap for 30 seconds, even when they are not firing their weapon - unless players are using the UAV Jammer, Cold-Blooded, Assassin, or Ghost as perks. The UAV will update enemy positions every three seconds, and will last for 30 seconds. 10 experience points are earned for calling in a UAV Recon in Call of Duty 4: Modern Warfare. In Call of Duty: Modern Warfare 2, players receive 100 experience points for doing so.
