Can leaders choose who participates in a Clan War?

Added by popular demand, Clan Leaders and Co-Leaders may select who participates in Clan Wars to set up the ultimate team.

Pressing the “Start War” button brings up a list of all your Clan mates. On the right, you'll see a button that says “In” or “Out”. When you use this team selection tool for the first time, the “In/Out” button indicates each member’s personal preference. As a Leader or Co-leader, you have the right to override this preference.  The War selection screen will display each player's preferences prior to each new Clan War. Toggle them with discretion and create your ideal fighting force.  

Clan War match-ups can only be made in increments of 5 members, i.e. 5 vs 5, 10 vs. 10, 15 vs. 15, 20 vs 20, 25 vs. 25, 30 vs. 30, 40 vs. 40 and 50 vs. 50. In the Clan War selection tool, the villages that will ultimately participate in the war are shown in green (set to "In"). Furthermore, if your clan has 17 members with their preferences set to “In”, you must manually set 2 users to "Out", in order to fairly match the opposing Clan. This means your clan will be matched in a 15 vs 15 Clan War. If you set all 20 to "In", you will be matched up 20 vs 20.
