There was Semtex used in big chunks like C4 (I saw it on Deadliest Warrior) and I do not think there has been a sticky semtex grenade invented back then. . . or today.

Surprising how they went from extremely accurate World at War to. . . this. It really turns me away from the game, and also the hackers and multiplayer. I know it doesn't matter, but I like things to be right and not to teach 12-year-olds that people were running around with red dot sights and under-barrel grenade launchers in Vietnam.

Also, the masterkey was invented in the 80's, I believe.
