Corelyn would likely be warned ahead of time due to her retooled magitek companion, Bit, and would very likely panic and, depending on what she has on her person, either dive for cover or activate some kind of magitek device to shield herself from the attack. She'd know full well why someone would want her dead: she's Garlean. She's a citizen of the enemy's land, a deserter, and a traitor to her formerly-beloved Garlemald. Both sides could just as easily gun for her.
Dail'a, on the other hand, would likely be distracted, as he frequently is. While, being a miqo'te with rather sharp senses, he'd have at least some inkling as to something flying at him at a high speed, it wouldn't be until it was too late. He'd likely wind up taking it in a generally non-fatal area, then immediately proceed to scream all manner of curse words before snapping the shaft and getting ready to murder the hell out of something.
