Dusk Phase: Attack & Defend (19:00–20:30)Factions will alternate between attacking and defending critical SAM sites. The attackers will start with a bomb that they are to escort and detonate on their choice of two enemy SAM sites. At the target site, the attackers should set down their bomb within five feet of the target site's glow stick, press the button to activate the audible five-minute countdown, and protect it from enemy contact while it counts down to detonation. If the attacker carrying the bomb is hit, they must drop it immediately, but the defenders may not pick it up. Instead, they may set up a perimeter around it to prevent the attackers from retaking it. Once the bomb has been activated on a target site, it may not be moved by either faction.The defenders are to prevent the bomb from detonating on either of their target sites. They may prevent it from getting there or defuse it by pressing the button for 15 seconds after the countdown has started. If the defenders defuse the bomb, the round ends. Each round has a time limit of 30 minutes. The attackers will earn 200 points if their bomb detonates on a target site. The defenders will earn 200 points if they prevent the bomb from being activated on a target site through the end of the round time. If the bomb is activated on a SAM site and successfully defused before the five-minute countdown ends, the defenders will earn 250 points. If the bomb is activated on a target site within the last five minutes of the round, the time limit of the round will be extended until the bomb is either detonated or defused.For Round 1, NATO are the defenders. They must start from their self-respawn at Gravesite and rush to defend their two SAM sites at Main Bridge and the center of the Valley. Meanwhile, USSR are the attackers and must start with their bomb from their self-respawn at Campbell.For Round 2, USSR are the defenders. They must start from their self-respawn at Bragg and rush to defend their two SAM sites at Adams and the Pond. Meanwhile, NATO are the attackers and must start with their bomb from their self-respawn at Drum.Prior to the starting of each round, the defenders will have one minute to disperse and prepare their defenses.
