Rambo mainly kills hostiles, rather than defenseless non-combatants face to face, though he doesn't seem to mind strafing an entire village. While there are "good" Vietnamese shown (mainly Rambo's love-interest), most are enemy slave drivers or pirates. Russians are torturing sadists. Elements of the U.S. military portrayed as untrustworthy worms.
Blood-spattered shooting. Characters pierced with arrows and blown up with bombs, torched with fire. A character tortured with electrocution, beating, hot metal, threatened eye gouging. Villages and war machines exploded. A U.S. military office sprayed with machine-gun ammo.
Vietnamese prostitute is a distraction in the enemy camp, and there's a towel-clad girl on a pirate ship, but nothing explicitly shown.
"Bastard" and the f-word once, spoken by Rambo.
Coca-cola machine is prominent.
