The MRE Prank
Written/Narrated by: Ed Bejarana | Published on: July 21, 2025
A Cold Night, a Loud Pop, and a Grumpy Sergeant
For those who’ve served, the MRE (Meal, Ready-to-Eat) is more than just sustenance; it’s a symbol of field life, a source of endless jokes, and, for the truly mischievous, a component in a classic military prank: the “MRE Bomb.”
This well-known, harmless prank was a favorite during downtime, especially when boredom set in. It leverages the simple chemical reaction of the MRE’s flameless ration heater. Remember those? You’d add a splash of water to the heater packet, and it would warm your meal through an exothermic reaction, producing hydrogen gas. The “bomb” part comes in when soldiers would seal that activated heater, with a bit of water, inside an empty plastic bottle. As the gas built up pressure, the bottle would eventually burst with a loud, startling pop. It was designed purely for noise and surprise, a harmless explosion that often led to uproarious laughter and the start of many a legendary “prank war” among units.
To truly appreciate the spirit of these makeshift diversions, let’s revisit a cold night where two enterprising privates decided to bring a little unexpected excitement to their grumpy sergeant’s slumber.
The Grumpy Sergeant’s Rude Awakening
The wind howled like a banshee across the frozen tundra, rattling the tent flaps of FOB Wolverine. Inside, Sergeant “Grumpy” Miller, a man whose permanent scowl seemed etched into his very being by years of early mornings and late nights, was finally attempting to snatch a few hours of sleep. Every breath he exhaled misted in the frigid air, despite the efforts of a struggling portable heater.
Outside, in the biting cold, Privates first Class Jensen and Rodriguez huddled behind a supply crate, their faces illuminated by the dim glow of a tactical flashlight. Boredom, that universal soldier’s affliction, had set in hours ago.
“You got the water?” Jensen whispered, rubbing his gloved hands together.
Rodriguez held up a nearly empty, two-liter water bottle. “Just enough. And the heater.” He produced an MRE flameless ration heater, the crinkly packet feeling oddly substantial in his grasp.
Their plan was simple, yet brilliant in its mischievous intent. They’d heard the old tales of the “MRE bomb” – a harmless explosive concocted from the ubiquitous ration heaters. A quick splash of water, a sealed bottle, and the build-up of hydrogen gas would do the rest. Their target? None other than Sergeant Miller, whose nightly grumbling was as predictable as sunrise.
With practiced efficiency, Jensen tore open the heater packet and emptied its contents into the bottle. Rodriguez poured in a precise amount of water, just enough to activate the chemical reaction. Then, with a conspiratorial grin, Jensen screwed the cap on tight, giving it a final, decisive twist.
“Okay,” Jensen breathed, “Operation Wake-Up-Grumpy is a go.”
They tiptoed to the side of Sergeant Miller’s tent, the snow crunching softly under their boots. Jensen carefully placed the bottle against the tent wall, right next to where Miller’s cot would be. They then retreated to their hiding spot, shivering not just from the cold, but from anticipation.
Minutes stretched into what felt like an eternity. The wind continued its mournful song. Then, just as Rodriguez was about to suggest it had been a dud, a deafening THWACK! ripped through the stillness of the night. It sounded like a rifle shot, magnified tenfold.
A guttural roar erupted from inside Miller’s tent. The canvas flapped violently as the sergeant, yelling incoherently, burst out, weapon in hand, scanning the darkness with wide, panicked eyes. “What in the unholy hell was that?! Incoming?!”
Jensen and Rodriguez, unable to contain themselves, burst into uncontrollable laughter. Their cackles echoed across the desolate landscape, cutting through Miller’s bewildered shouts. The sergeant spun around, his eyes narrowing as he finally pinpointed the source of the amusement. The shattered remains of the two-liter bottle lay innocently in the snow near his tent.
His face, already a landscape of perpetual displeasure, now contorted into a mask of pure, unadulterated fury. “JENSEN! RODRIGUEZ! GET YOUR SORRY HIDES OVER HERE, NOW!”
The two privates, still chuckling, slowly emerged from behind the crate, bracing themselves. They knew the reprimand would be loud, perhaps even involve some extra duty, but the sheer joy of seeing Sergeant Miller’s startled face made it all worth it. As they approached, Miller’s voice boomed across the camp, promising retribution that would make their lives a living misery. Yet, beneath the bluster, a faint, almost imperceptible tremor of amusement seemed to flicker in his eyes. The prank war, it seemed, had just begun.
