[Onslaught/Swindle/Brawl, Fuka Japan, Nighttime]
The Combaticons detected an alarm go off nearby. They approached the building it was emanating from, and scanned it. No doubt this was the place that Soundwave had detected. They would proceed with a smash and grab once they conducted a thorough scan of the building. In a about minute that would be complete, so all they had to do was wait.

[Vortex/Blast Off, Fuka Japan (high altitude), Nighttime]
The two flyers of the Combaticons, Vortex and Blast Off, were flying around at high altitude. Their mission was to keep an eye out for any enemy reinforcements, to intercept said reinforcements before they reached their peers, and to act as air support and backup when needed. Onslaught was a good tactician, and knew what he was doing. Nevertheless, it was boring flying around and doing nothing. They soon found themselves hoping that either they would be discovered and get some action, or the primary objective would be completed very shortly.
