US Army anti-drone manual: freeze, no phones, sandbags

US Army teaches soldiers to freeze when a drone appears

A hum in the sky turns the soldier into a statue. This is not rhetoric but the first instruction of the US Army's counter-drone defense manual, which orders activity to stop immediately upon detecting an unidentified aircraft overflying the unit. The text describes a scenario that has ceased to be science fiction: small, cheap, silent drones capable of deciding a position before anyone sees them. Analysis of how today's war is fought in Ukraine builds on this foundation.

The starting point is uncomfortable. Category 1, 2, and 3 drones are undetectable by radar, so surprise is not a possibility but the norm. The manual itself admits such devices are "very difficult to observe in flight," even for trained eyes, noting that light, weather, and observer fatigue condition any detection. When the soldier spots it, they are already targeted.

Why does the soldier freeze when a drone appears?

Because moving, starting an engine, or firing makes the unit visible. Doctrinal reaction to an unidentified device is immobility, based on the logic of suspecting prolonged observation. Immediate contact is assumed thereafter.

Simultaneously, the manual prohibits shooting at everything flying: the same drone model may belong to both sides, and downing a friendly one is costly. The alternative is aiming ahead, like duck hunting, maintaining the point without correction. A football field rule is proposed to calculate lead based on size. A conversation idea emerges: some note the captured device looked like a €20 toy drone bought online.

Trenches, sandbags, and full-spectrum camouflage

Camouflage ceases to be visual. ULCANS nets cover the entire electromagnetic spectrum, not just visible light, requiring obsessive use: the manual warns one careless soldier compromises the whole unit. Hence, return to buried routines: no fires, no vehicle heating, no open hoods, remove smartwatches, phones, headphones. UV sensors added in snow.

Doctrine recovers two old principles. First, maximum dispersion, inherited from divisions designed for nuclear battlefields in the 1950s, except in dense forests and urban areas where vegetation or buildings allow grouping. Second, hiding under trees, exactly what Germans did in Normandy in 1944 to avoid aerial sweeps. The novelty is Americans now practice it too.

On the ground, protection becomes artisanal: layers of sandbags and steel plates on vehicle and building roofs against falling grenades. Israel has installed such structures on Merkava tanks and other armored vehicles. The manual suggests, if resources permit, an uncomfortable test: using own drones to check visibility of one's position.

Why artillery returns as queen of war

Here lies the argument changing conflict reading. A drone does not only kill: it observes. Fire data provided on enemy positions is devastating, making indirect fire approximate direct fire. This returns artillery to the board center, explaining why fronts have stalled again as in 1914.

Historical comparison is not ornamental. Current kamikaze drones with handmade grenades and impact fuzes resemble 1915 aviators dropping bombs by hand from biplanes. That was curiosity; this is the main tool of attrition warfare.

Do drone jammers work?

They work intermittently, the material's conclusion. Drone Buster type equipment requires sustained aim; other jammers promise disabling "many" drones with unspecified autonomy. Reasonable suspicion exists: unknown what truly works. As a participant notes, those trinc weapons procurement know promises rarely meet reality, judging acquisition systems no cleaner here than in Russia.

Technical problem is physics, not will. FPV drones reach 100 km/h before impact; videos show signal loss just before hit while device continues arriving. Deviating from commercial frequencies, using unusual bands, or optical links disable current jammers.

Swarms, AI, and end of foot infantry

Race is no longer about isolated devices. Scenario drawn involves drones with onboard decision capability, no ground control, and swarms facing each other before a single soldier appears. Some calculate ten AI devices could eliminate an 80,000-person city population in hours; counter-drone specialists already part of unit rosters, like snipers or machine gunners previously. Nineties sci-fi warned: buzzing flying insects in Starship Troopers sound suspiciously like quadcopters today.

A soldier neglecting camouflage compromises their unit. And a device costing two daily menus decides a position's outcome. Hard to sustain war is men's affair when winner is one who doesn't breathe.
