The last military transport I flew on was a C-141 back in 2002. The plane was fitted with airliner-style seats, but those seats were facing towards the rear.
Just depends on what it's carrying. I've flown on C-17s that have airline seats on pallets. Other time we had cargo so it was the seats along the side, which also suck.

These things suck to fly on when you're only option is to sleep on the floor that's too cold.
