I don't think they are passives since on the KLTwebsite they are dark blue like second job attack skills and are located under the Weapons Skill Tab as opposed to the Misc Skill tab.
Both of their skill images is of some dark figure. One has a firelike aura around it, the other has what looks like a force field around it.
EDIT: Airstrike must be extremely strong because apparently the last version of it is obtained at level 190 e_e
EDIT2: After closer inspection apparently both are in the video
ReCharge (It's in the Red Sqaure)
They're just used too quickly so they look like they are a part of the Airstrike Skill but they actually aren't.
