Announcing The Veteran's Challenge

MrDad, on Oct 31 2012 - 12:24, said: My clan would like to join in the tier 6 challenge, but we don't understand this part.....
With maximum number of 5 players per battle, a team (up to a maximum of 6 players per team) must field a selection of tanks based on the below tier limits. Teams are also limited to a maximum total of 26 tier points
Does this mean that 4 players use T6 tanks(24 tier points) and 1 uses T2 (2 tier points) to make up the 5 per battle? Or do we use only 4 tier 6 tanks? Your help would be much appreciated by our ever growing clan.
