IIRC the only time Martaugh saved Rigg's life was in LW4 against Jet Li. the funny thing is though that the worst bumps that Riggs took were with Martaugh right there but still failing to get his back (Lw2 when the dude emptied the whole f'ing clip on Riggs for example). Martaugh always had his own agendas in the movies and he was more the second hero than the sidekick. also, Riggs' villains weren't conceited schmuks who liked to toy with their prey. neither laurna nor Martaugh saved Riggs' bailed Riggs out from certain death at any point (except an old riggs against Jet li). Riggs literally took out the entire base of the badguys ON HIS OWN in LW1 and LW2. there is no scene in LW series where Riggs' couldnt' have survived without Martaugh or anyone else. heck, Riggs was originally supposed to die at the end of LW2 because martaugh didn't have his back when he got shot. in the novel he actually dies.
the cop friend of McClane saved his life and his wife's life in the end of DH1. Zeus literally dragged McClane's ass out of the fire at that harlem scene. then it was Zeus who helped with their untying which ALSO would've ended in McClane being charblasted outta the world. and the computer geek was somebody who filled in mcclane with all the tech knowledge you can think of cuz there is NO WAY mcclane would've been able to figure everything out on his own cuz he knew next to nothing about computers. i don't remember DH2, but McClane probably had his ass saved there too. face it, boys and girls, McClane's been VERY lucky in all his hero cop charade.
