M2 Browning In Space
Published September 11, 2026
M2 Browning In Space, also known as the Ma Deuce Mars Copypasta, is a 2016 4chan greentext about a soldier fighting rebels on Mars in 2066 with a WWII-era .50-caliber machine gun. The joke lands because the real M2 Browning, designed by John Browning in the 1910s, is still standard-issue across NATO militaries. The post grew into a long-running running gag on /k/ and Reddit gun boards through the 2020s.
Overview
M2 Browning In Space, sometimes called the Ma Deuce Mars Copypasta or simply the M2 Browning Copypasta, is a first-person greentext told by a soldier serving as a door gunner on an atmospheric dropship above Mars in the year 20663. He mows down rebels armed with plasma guns and compact rocket launchers, then glances down at his weapon and reads the receiver stamp: manufactured 1942, with the campaigns 'Tunisia,' 'Italy' and 'Germany' engraved on it3. He adds 'Mars' to the list. The joke works because the M2 Browning .50-cal, nicknamed the Ma Deuce, is a real-world heavy machine gun designed by John Browning during World War I and adopted in the 1930s, and it is still the primary heavy MG for the U.S. military and most NATO forces almost a century later1.
A follow-up 'part two' by another anonymous poster extended the same bit into a farther-future war against aliens, cementing the format as a template for 'the M2 will outlive us all' jokes3. Later variants swap the setting or the enemy but keep the punchline: whatever century the story is set in, the door gunner is still spraying .50 BMG from a piece of hardware older than his grandfather. The bit is a favorite on /k/ and adjacent weapons communities because it turns a real quirk of U.S. procurement, the M2's stubborn refusal to be replaced, into a science-fiction gag1.
