When Niner finally reached the top of the building, he threw his DC-17 on the floor to let the Republic mercenary and jedi know he was unarmed, though he most definitely wasn't. He turned off his helmet comlink, so he could talk to them. "Get down into the building!" he yelled to them.
He retrieved his rifle and ducked back into the safety of the building. He hoped that the troopers would follow him. After all the commotion Alpha Squad had caused, every Sepratist sniper on Mygeeto was probably scanning the building.
