When and where

Gaijin’s announcement schedules the event from October 16 at 11:00 UTC until October 19 at 11:00 UTC. It appears in the hangar’s Events & Tournaments menu under Suppression of Enemy Air Defenses.

One side attacks S-75 surface-to-air missile positions while the other protects them. Aircraft and helicopters play different roles; AI anti-aircraft vehicles add another threat around the defended positions.

Rules that change the approach

The mode generally removes enemy markers and gives each player three respawns. The announcement requires a rank V or higher aircraft in the player’s hangar, but assigns the event vehicles rather than requiring those particular vehicles to be purchased.

Gaijin says anti-radiation missiles were excluded from this event after testing. This briefing summarises the announced rules and time window, not current queue availability. Check the date before planning a session, because an archived event notice is not an always-available game mode.
