Sitrep helps you see glowing red claymores, tactical insertions, and grenades through walls.
Sitrep Pro does the same but it also increases the sound of enemy foot steps, and you can also hear enemies footsteps even if they are using Ninja Pro (which gives them silent footsteps).
+rep if helped.

Sit Rep: Works like Bomb Squad from COD4 it lets you detect enemy explosives and tactical insertions but it is much more advanced because now they highlight red and can be seen across a map.
