"Instantly Scan for intelligence on impact, in a sizable area."
— In-game description

The Scan Grenade is a Tech Tier 3 gadget featured in Tom Clancy's Rainbow Six Extraction. It is available to unlock with a REACT Token at Development Milestone 12.

Once thrown, it detonates on impact and scans all Archæans (including cloaked Archæans) as well objectives within a 12 meter radius for 30 seconds. A total of 4 grenades are carried initially while more may be carried through a REACT Tech resupply.

Scan grenades are valubale for defending areas around objectives or extraction points as they notify players of incoming enemy locations without the need to control a drone or use an Operator ability.
