Inflatable tanks and flat-pack guns - inside Ukraine's decoy war

In June 2023, a video started spreading on pro-war Russian social media channels, apparently showing a drone destroying a Ukrainian tank in a massive explosion.

But not everything is what it seems in the Russia-Ukraine war.

That video was followed by Ukrainian footage showing a laughing soldier pointing at the burning wreckage and exclaiming: "They've hit my wooden tank!"

The tank in question appears to be a plywood decoy used by the Ukrainian forces to deceive the Russians.

It is one of many thousands of full-scale models of military equipment used by both Ukraine and Russia to trick the enemy into wasting valuable ammunition, time and effort.

Almost anything seen on the frontline - from small radars and grenade launchers to jeeps, trucks, tanks and actual soldiers - may be fake.

These imitations can come in flat-packs, be inflatable, 2D or create a radar illusion of a tank by reflecting radio waves in a special way.

In the case of some weapon types deployed in Ukraine, at least half of them are actually decoy imitations.

Russia often targets them with Lancet kamikaze drones costing about $35,000. "You do the math", Mr Narozhny says.

One of his M777 decoys, nicknamed Tolya, has spent more than a year on the frontline, surviving hits with at least 14 Lancets, he claims.

Troops "keep putting it back together with some sticky tape and screws, and back off to the frontline it goes", Mr Narozhny says.

Much depends on how decoys are deployed. To successfully draw enemy fire, it helps to faithfully recreate a real position complete with wheel ruts, ammunition crates and toilets. When properly done, this can deceive not just the enemy, but visiting officers too.

"We had an instance in one brigade where a visiting commander was fooled by a decoy: He asked: 'Who gave the order to deploy artillery? Where did the M777s come from?'" says an officer from Ukraine's 33rd Detached Mechanised Brigade, who uses the callsign Charisma.

According to him, another tactic is to quickly remove real cannons such as mortars after use and replace them with decoys.

"They're ideal for deceiving the enemy and making them waste expensive resources on nothing. They work, we need more of them," he says.

Russia's arsenal of decoys is also rich and varied.

About half of the drones involved in any of Russia's recent aerial attacks are actually cheap imitations, the Ukrainian military says.

"It's fifty-fifty these days. Fifty per cent are real Shahed drones, and fifty per cent are imitation drones. Their job is to overload our air defences and ideally get us to use a missile against a drone that costs peanuts," says Ukrainian air force spokesman Yuri Ihnat. "Sometimes it's a plywood thing that looks as though it was knocked together by some schoolchildren."

While up in the air, however, it looks the same as a lethal Shahed drone to Ukrainian radars, Col Ihnat says.

One Russian firm, Rusbal, produces imitations that include 2D decoys to mislead intelligence gathering from the air or space, decoys that mimic the heat given out by engines or radio traffic coming from soldiers' walkie-talkies, and reflectors that fool the enemy's radars.

Actual soldiers can be imitated too. Volunteers from the Kremlin-backed People's Front movement in Novosibirsk have made dummies wearing military uniforms. To imitate human heat and thus deceive Ukrainian thermal imaging cameras, their trunks are wrapped with heating wire underneath the jacket.

But of course, decoys are not a new idea in war.

In preparation for D-Day landings, an entirely fake army group was set up in the UK, equipped with dummy tanks and decoy aircraft.

It was all part of an elaborate trick to hide the reality on the ground and give the Allies the element of surprise they needed to launch their attack.

Military technology has hugely improved since World War Two. Drones and unmanned systems on the battlefield are a major innovation in this war, for instance.

But no matter what new weapons of destruction make it to the battlefield, it just goes to show that subterfuge and trickery – even with something as simple as a blow up doll - will always play a part in warfare.
