Since esteemed leader gives Corp troopers

guardian 1 within range one .

if you have 2 units within range one of veers with esteemed leader does that mean 1 hit per unit ( 2 total) are allocated to stormtrooper or is it one hit per attack allocated to stormtrooper?

Esteemed leader gives two trooper units within range 1 guardian 1. So yes, both of those units could negate one hit each from Veers.
