History of Counter Attack

Counter Attack is a Countdown medal triumph: "Defeat an opponent within 5 seconds of them setting a charge."

How to complete

• Countdown is a 4v4 Crucible mode with attackers who arm a charge at a site and defenders who stop it. Arming takes about 3 seconds and the charge detonates after roughly 40 seconds (Destiny Game Wiki).
• You need to be the defender (or on the other team) who kills the player who armed it within 5 seconds of that arming. Stay near the sites and stack on them (Ten Ton Hammer's defender advice), so you can punish the planter immediately.
• Progress is tracked as medals earned.

The sources opened did not describe this medal itself, so exact tracking details are unconfirmed.
