At the meeting before the operation to capture the high value target, one of the Delta guys gets up in Kate's space as he walks past as some kind of weird alpha macho guy move.
After the op, Kate is smoking a cigarette back on the American military base and the same Delta guy walks by and asks her "You like fireworks? Wanna see something cool?" He then takes her up to the roof to see the chaos they caused.
She earned his respect and all she had to do was smoke a dude!
