Looking for a short story about a soldier in the future on a mission. At a certain point he bites down on a banana shaped capsule under his tongue and the drug accelerates his metabolism for the mission. at the end he lies with the other soldiers twitching and burnt out on the ground waiting for recovery, Prob 1950's or 60's. Thought it was called "Soldier, Soldier" but can't find it. It was not "Soldier of the future" Thanks

The soldiers are enhanced by the use of various drugs. They go out on a mission while carrying a special boomerang shaped drug capsule under their tongue. Upon command, they eat the drug, which gives them hyper-speed. They run so fast they are difficult to be targeted, and they can pull the trigger of their weapons much faster than the enemy. Side effect is it caused the sound of gunfire to damage their hearing.
