Senjen did not have too much difficulty bracing. Even with the force of the truck crashing its way out of the garage, he could wedge himself in place quite nicely. However, that meant he could not be doing anything else but waiting for the truck to straighten out. Some of the other soldiers had to struggle to keep their wounded comrade stable through all the jostling, but none of the rest of them were hurt, at least. Still, the enemy was not going to give up for a moment.  He could not stop, could not rest. At least not yet. 

Once the truck was stable again, Senjen was already heading right back to the hatch. Initially, it was to help out the truck behind them, as he had saw some of the droids climb onto it. However, he had more immediate concerns when an explosion shook the whole truck and the hatch was ripped off of its hinges. Senjen was stood front-and-center, pistol raised, when he saw the quick flash of a metal hand at the edge of the hatch as something was thrown inside. With where he was positioned, there was immediately a loud [i]clunk[/i] when the small object struck Senjen right in the face. 

Senjen was capable of feeling pain, but mostly he was just startled. The impact canceled the object’s forward momentum, so it floated for just a moment in front of his gaze before he swatted it directly away from himself in a mild panic.
