Tau Battle suits question

[andarin]

hello i have a Question about Tau

if a squad of three Crises Battlesuits are firing at a target and one of them has a target array (+1 BS) do all 3 fire at BS4 or just that one unit?

if possible can you show me evidence

Just the one suit with the targeting array gets the BS buff, since that particular piece of wargear doesn't specifically give the team the bonus. BRB, pg. 18.
