the man in the hospital is operated on and we see a lot of blood
A healthy amount of stabbings with swords (including a creative one from unusual angle, and one with a handheld arrow!), a couple of vaguely intense fight scenes.
Three actors playing ex US Marines participate in combat, showing resourcefulness combat skills significantly below what mid-20s female archaeologists are apparently capable of.
Man has ear cut off (not very visible).
"Explosions" all but one via trebuchet/catapult.
Lots of arrows
