Oscar Mike to the glossary. Copy that.
A GPS-enabled combat identification system that displays friendly troop positions in real-time on digital maps, theoretically preventing you from shooting your buddies. The military's answer to "Find My Friends" but with significantly higher stakes.
Enemy combatant has been neutralized or killed. The phonetic alphabet's contribution to making lethal force sound like a radio frequency update.
Communications Security—the art and science of keeping your radio chatter from being intercepted, decoded, and used to ruin your whole day. Loose lips sink ships, encrypted lips just confuse everyone.
A scheduled period of duty, particularly aboard ships or in security operations. Borrowed from nautical tradition, it's why military personnel measure their lives in four-hour increments of consciousness.
The specific hour on D-Day when an operation begins, the synchronized moment when everyone stops planning and starts executing. The military's equivalent of "go time" but with more precision and consequences.
The collective noun for all the expensive ways humans have invented to hurt each other, from bullets to battleships. It's the military's shopping list—cannon, small arms, missiles, and whatever else makes defense contractors salivate. Basically, everything that goes 'boom' or 'bang' in a military context, neatly categorized for budgetary purposes.
Simultaneous planning at multiple command levels while higher headquarters is still developing their order, allowing faster execution. Starting your homework before the teacher finishes explaining it, but with explosives.
Opposing Force—the designated enemy in training exercises, or actual adversary forces in planning. The people whose job is to make your day difficult, whether for practice or real.
A secure area under friendly control, where the risk of attack is low enough that you might actually sleep through the night. Not to be confused with the heavily fortified government district in Baghdad, which took the name but added way more blast walls.
A stepped arrangement of units where each is positioned diagonally behind and to the side of the one ahead, creating a staircase pattern. Geometry class suddenly becomes relevant when you're trying not to shoot your buddy in front of you.
Either a person wielding a firearm, a video game genre focused on shooting things, or a small glass of alcohol designed to get you drunk efficiently. In military and law enforcement contexts, refers to someone actively using weapons. In gaming, defines an entire category of games where pointing and clicking on enemies constitutes gameplay. Context is everything with this one.
Everything you load into a weapon to make it useful—bullets, shells, rockets, and other implements of persuasion. In broader terms, it's also the metaphorical arsenal of facts, arguments, or dirt you've collected to use against someone in a debate or conflict. Because sometimes words are weapons too, just significantly less regulated.
A flexible combined-arms formation built around a core unit (battalion or regiment) with attached supporting elements like armor, artillery, and engineers. A military Lego set where you snap together different capabilities based on the mission.
A five-sided polygon that geometry teachers love and students tolerate, but more importantly, the nickname for the massive five-sided building that houses the U.S. Department of Defense. When someone says "the Pentagon decided," they mean the military brass made a call, not that a geometric shape achieved sentience. It's the ultimate example of form following function, or maybe just a really committed geometry flex.
A veteran service member with extensive experience, often multiple combat deployments. Has seen it all, believes none of it, and maintains emergency coffee supplies.
A large military formation of tens of thousands of troops, typically composed of multiple divisions and commanded by a lieutenant general who has a lot of people to disappoint. Also used by organized groups who want to sound more official and disciplined, like the Marine Corps or the Peace Corps. It's pronounced 'core' because the French spelling loves watching English speakers struggle.
Military training operations where troops practice warfare without the actual dying part. These simulations range from small-unit drills to massive multinational operations involving thousands of personnel. It's like a very expensive, very serious rehearsal where everyone hopes opening night never comes.
Operating in secret mode, typically used for law enforcement or intelligence work where revealing your true identity would ruin everything—or at least make the sting operation really awkward. It's like being a spy, but with more paperwork and fewer martinis.
The proportion of combat forces (teeth) to support personnel (tail) in a military organization. A measure of how many people with guns you have per person carrying clipboards and fixing trucks.
Authorization to engage any target that meets rules of engagement criteria without requesting permission. The green light for 'shoot first, ask questions later'—within legal boundaries, of course.
Military acronym for "Bend Over Manchu, Here It Comes Again"—a variation of BOHICA used by U.S. soldiers stationed at Camp Hovey in Korea. Refers to the special kind of repetitive misery that comes with military assignments, now with geographically-specific flavor.
When something is so thoroughly destroyed or removed that it's basically been deleted from existence in that area. More intense than just 'eliminated,' this term suggests roots and all—whether we're talking about literal stumps, enemy positions, or unfortunately, entire populations. It's the scorched-earth version of 'getting rid of something.'
A specific method of tightly rolling clothing into compact cylinders for efficient packing, named after Army Rangers but taught across services. Makes maximum use of limited space in rucksacks.
Acronym for "Situation Normal: All Fouled Up" (or a more colorful variant), describing the military's natural state of controlled chaos where nothing works quite as planned but everyone pretends it's fine. A philosophical acceptance that Murphy's Law is the only reliable constant.
