We were asleep in our cots at Bagram Air Base in Afghanistan when exploding enemy rockets woke us up. My platoon and I threw on our fatigues, grabbed our weapons and ran to the bunker for protection. Inside the bunker, one nervous soldier lit up. “Put that cigarette out!” I ordered.

“Yeah, forget the rockets,” said another soldier as more rounds rocked the bunker. “That secondhand smoke’ll kill ya.”
