An old Navy Chief and an old Marine Gunny were sitting at the VFW arguing about who'd had the tougher career. "I did 30 years in the Corps," the Marine declared proudly, "and fought in three of my country's wars. Fresh out of boot camp I hit the beach at Okinawa, clawed my way up the blood-soaked sand, and eventually took out an entire enemy machine gun nest with a single grenade. As a sergeant, I fought in Korea alongside General Macarthur. We pushed the enemy inch by bloody inch all the way up to the Chinese border, always under a barrage of artillery and small arms fire. Finally, as a gunny sergeant, I did three consecutive combat tours in Vietnam. We humped through the mud and razor grass for 14 hours a day, plagued by rain and mosquitoes, ducking under sniper fire by day and mortar fire all night. In a firefight, we'd fire until our arms ached and our guns were empty, then we charge the enemy with bayonets." "Ah", said the Sailor with a dismissive wave of his hand. "Lucky b*stard, all shore duty, huh?"
