Stealth Coating is an air vehicle specialization in Battlefield 4. It functions in a similar manner to that of the Battlefield 3 counterpart, forcing enemy combatants to take more time in acquiring a successful lock-on to the operator's vehicle. This can be useful if the player is actively performing Hit-and-Run tactics, allowing them to escape the area before a lock-on can be achieved by hostiles.
