A GENERAL or MAJOR GENERAL of an ALLIANCE can initiate a SeekNDestroy on an opposing SeekNDestroy. The opponent ALLIANCE is automatically selected on the matching levels of your individual ALLIANCE members. A new ALLIANCE is given 2 weeks of protection from getting attacked by other players using SeekNDestroy. An ALLIANCE can use this time to get more powerful.
The game suggests opponents based on the average level of top 5 level players in your ALLIANCE which becomes your SnD Level.
The attacker ALLIANCE (SnD initiator) can fight only the members from the defending ALLIANCE within their fighting range. Defending ALLIANCE can fight any member of the attacker ALLIANCE irrespective of level range.
