"Got it." 
Kai, unfazed by the sudden switch from banter to battle immediately unshouldered his Light Machine Gun. As he was by the window, it didn't take long for him at all to get the window edge as a nice convenient stand for the LMG and quickly loaded it with a clip.

He began firing in short bursts at the cargo hold of the truck, aiming to suppress them and to prevent the guy holding the bazooka from getting another shot without Kai being able to instantly pepper him with bullets if need be.
