"Usually" Team tournaments treat both partners as 1 army, with 1 player turn.
However this is dependent on the TO. If they have stated that each player army act indepently and gets their own turn then yes, you get to apply it twice.
However this would make for a very long game as you would have player 1A move, shoot, charge, player 1B move, shoot, charge, player 2A move, shoot, charge, player 2B move, shoot, charge.
TL;DR: ask your TO
