Why The Infantry Company Is No Larger Than 150, According To A British Soldier

The Long March

150 is about as large a group of people as the human brain can handle in personal relationships, notes a British military commentator.

The story of the importance of stories begins not in leadership, but in anthropology. Robin Dunbar is a British anthropologist, evolutionary psychologist and a specialist in primate behaviour. In the 1990s he identified a correlation between the size of the pre-frontal cortex in ape species and the size of the social groups each species could maintain. If you took the size of an ape's brain, you could calculate the size of its social group size. This number – the maximum social group size for a given species, based on pre-frontal cortex size – became known as the Dunbar Number.

Hence the limit on the size of an infantry company, he says, as well as on Stone Age farming villages and new religious sects.

Human civilization is about fire. Creating fire is what separates us from the animals; extinguishing it without urinating on it, according to Sigmund Freud, marked the starting point for the most fundamental societies. It is also, at its core, a force of destruction — and, therefore, a weapon of war.

Anyway.

Army researchers have devised a method to produce ceramic body armor, lightweight but strong, from a 3D printer. Except that 3D printers are meant to print out knickknacks, not flak jackets — which meant that engineers had to hack into the printer to get the job done.

There are #squadgoals, and then there are squad goals — and only one of them includes a potential future accompanied by autonomous murderbots.

Hot on the heels of the Marine Corps's head-to-toe overhaul of infantry rifle squads, a handful of grunts at the Air Ground Combat Center at Twentynine Palms, California recently conducted field testing alongside a handful of autonomous robots engineered by the Defense Advanced Research Projects Agency's (DARPA) Squad X Experimentation program.

Navy SEAL Chief Eddie Gallagher dodged the most serious charges the Navy threw at him during his court martial, but his final sentence could be far worse than what the jury originally handed down.

If the convening authority approves the jury's sentence of four months' confinement and a reduction in rank from E7 to E6, Gallagher will be busted down to the rank of E1, according to Navy officials.
