Yogendra Singh Yadav was a member of an Indian grenadier battalion during a conflict with Pakistan in 1999.
Their mission was to climb "Tiger Hill" (actually a big-ass mountain), and neutralize the three enemy bunkers at the top. Unfortunately, this meant climbing up a sheer hundred-foot cliff-face of solid ice. Since they didn't want to all climb up one at a time with ice-axes, they decided they'd send one guy up, and he'd fasten the ropes to the cliff as he went, so everyone else could climb up the sissy way. Yadav, being awesome, volunteered.
When he reached the top, one of the target bunkers opened fire on him with machine guns. Yadav ran toward the hail of bullets, pitched a grenade in the window and killed everyone inside. By this point the second bunker had a clear shot and opened fire, so he ran at them, taking bullets while he did, and killed the four heavily-armed men inside with his bare hands.
Meanwhile, the remainder of his squad was standing at the top of the cliff staring at him saying, "dude, holy shit!" They then all went and took the third bunker with little trouble.
For his gallantry and sheer ballsiness, he was awarded the Param Vir Chakra, India's highest military award. Unlike the Medal of Honor, the Param Vir Chakra is only given for "rarest of the rare gallantry which is beyond the call of duty and which in normal life is considered impossible to do." That's right, you actually have to break the laws of reality just to be eligible.
It was initially reported that Yadav had as well, but it turns out that they just mistook him for someone less badass. Or they just figured no real human being could survive a broken leg, shattered arm and 10-15 fresh bullet holes in one sitting.
