— In-game Description

The Recon Vapor Device is a Tech Tier 4 gadget featured in Tom Clancy's Rainbow Six Extraction. It is available to unlock with a REACT Token at Development Milestone 18.

Once thrown, it will detonate 2.5 seconds after impact, releasing vapor over a large area to scan enemies, including cloaked Archæans, for 45 seconds. A total of 3 grenades are carried initially while more may be carried through a REACT Tech resupply.

Like the Scan Grenade, they are great for defending areas around objectives or extraction points by notifying players of incoming enemy locations without the need to control a drone or use an Operator ability.
