I’m sitting on a blue plastic, wipe-down mattress with my back to a wooden pillar.

Ever since the invention of the two-handed club, warfare and technology have been inextricably linked. More often than not, the humans who are sent into battle have been mere pawns in these hi-tech contests. So we shouldn’t be surprised if the military are eying up one of the most exciting new technologies in neuroscience, noninvasive brain stimulation (NIBS), which uses electrical or magnetic fields to remotely influence the activity of particular parts of the brain and could boost physical and mental performance.
