Senjen and Light were moving quickly to keep up with the truck. He could see the droid hanging on to this side of the cabin, and he could see its drone was watching him. He could not sneak up on it to gain the surprise he had been relying on, though even at a quick glance he could see it was damaged. Flying in from behind, Senjen had to think on his feet. It was struggling with the Human up front for the girl and might have been prioritizing getting its hostage as the best way to ensure its success. That would have to be enough. 

Senjen had time to fire a shot before reaching the truck, but the shield easily absorbed it. With his feet, he grabbed a hold of the side of the truck just before it crashed through the window. The droid was just in front of him, so it took most of the glass shards and debris in his stead, not that it would have done much to affect either of them. Senjen had been relying on stealth and cleverness to get an edge on these droids this whole time, and he had one last trick that came to mind: a bit of misdirection and sleight of hand to deceive its threat assessment. While it was struggling over the girl, he fired another shot that the shield absorbed, then bashed the shield with the pistol grip in a vain attempt to break through. And while the drone watched his seemingly desperate attempt to force his way through up high, his other hand drew his own pistol from its holster down low. He pushed it slow enough to pass through the shield, intent on firing at the droid from within.
