Military technology has seen the least overt development, due to the centuries of relative peace. Infantry are the only humans on today’s battlefields, supported by remote-controlled armor, aircraft and land drones. Space-to-ground support is extremely dangerous and therefore not used by militaries due to the prevalence of surface-to-orbit weaponry. Soldiers are issued with rifles and pistols which fire incredibly thin, long penetrators at very high velocities with minimal recoil. The size of these projectiles allows hundreds to be carried in one magazine, and are highly effective when fired en masse. Small thin penetrators are not accurate over very long distances, so marksman rifles and dedicated sniper rifles have become even larger caliber, firing large explosive rounds to compensate for new armor technology. Advanced scopes are able to do all the calculations for the shooter by itself, reducing the required skill of the shooter and making soldiers much more accurate and reliable shooting over distances. Squad support weapons include anti-armor, high-impulse launchers, which fire massive, deadly projectiles. Man-portable grenade rifles are used to flush enemies from cover with timed airburst explosives. Combat is highly survivable due to new advances in easy-to-apply first aid, dispensed by fearless, durable robot companions. There are no energy weapons in the  Human armies, as power generation has not been miniaturized to such a degree as to be a viable replacement for ballistic weapons, however space ships and UAVs bring large laser emitters for point defense and medium-range anti-materiel purposes.

Space combat is going to stick to the soft sci-fi Nelsonian large fleet battles, with small fighters and bombers launcher from carriers supporting battleships and destroyers of all sizes, from a few dozen meters long to half a kilometer or more. Space engagements between humans occur at visual range, within a few dozen kilometers, due to massive advances in jamming technology. Most weapons are either large-caliber railguns, or banks of nuclear-tipped missiles. Fields that absorb kinetic energy punish small, fast projectiles, so modern military ships have been forced to move to bigger and bigger calibers of gun for ship-to-ship combat.
