So, knight to the right of Kylo holds a spear.
Knight to the far right has a gun.
All I keep seeing is that massive axe-looking thing held by 1st knight to the left, back of Kylo Ren. He's resting it on his shoulder. Massive... hopefully it chops up the resistance nice and sloppy. ;-)
Those are some menacing, ancient weapons from a bye-gone era.
