Brother in Arms bug
how do i change the perspective to TPP in veteran camp.

Solution
It is automatically selected based on the perspective your highest tier is in the current season. The only way to change it is to increase your tier in TPP.
So for example if Platinum 2 in FPP is your highest tier in the current season, you will need to reach Platinum 1 in TPP to be able to change the perspective.
