I figure the authorities are glossing over the truth as usual. Banging aircraft against each other is very dangerous. I highly doubt a Russian pilot would collide with a US drone to bring it down. They have a gun on a SU-27.
"The aircraft is equipped with a 30mm GSh-301 gun with 150 rounds of ammunition and a range of missiles, rockets and bombs mounted externally on ten hardpoints."
