In a recent blow to Russia, Ukrainian forces are taking out supply lines up to 50km behind enemy lines using a powerful fleet of drones.
The fleet, dubbed 'The Punisher', is being used to target fuel storage, electronic warfare stations, and ammunition supplies, and has been called 'game-changing' by the engineers behind the weapons.
The small, silent planes have a minute 2.2 metre wingspan - but despite their size, can carry up to three explosives.
However the innovative weaponry does not pose any risk to civilians.
They can reach up to 396 meters and can fly for several hours once airborne, and are accompanied by a smaller drone - called a Spectre - that identifies targets.
So far the unmanned planes, which are controlled from laptops on the ground, have already completed up to 60 'successful' missions since the invasion began.
The drone was developed by UA-Dynamics, a company launched by veterans who fought Russians during the Crimean annexation.
UA-Dynamics Engineer Eugene Bulatsev told The Sun that the laptop-manned drone's success is down to its is its 'stealth capability'.
"It’s relatively small and light enough to be undetectable to radar and you can’t see or hear it once it’s airborne which makes it a nightmare on the battlefield," he said.
"What’s more, it can drop three bombs at a time or hit three separate targets, then return to base to be reloaded and sent back into battle within minutes.
"We Ukrainians recognised that we needed a weapon like this having faced so much firepower for so long and have developed and improved it ourselves for six years."
In addition to The Punisher and its successful campaigns against Russia - the details of which are classified - Ukrainian forces also have access to about 20 Turkish drones, the Bayraktar TB2, according to Business Insider.
This comes amid reports that the Russian invasion is not going to plan, with Putin's troops 'suffering' according to reports by one of the UK's top admirals.
Speaking to the BBC, Chief of the Defence Staff Admiral Sir Tony Radakin said: "I think we've seen a Russian invasion that is not going well.
"I think we're also seeing remarkable resistance by Ukraine, both its armed forces and its people and we're seeing the unity of the whole globe coming together, applying pressure to Russia.
"Russia is suffering, Russia is an isolated power. It is less powerful than it was ten days ago. Some of the lead elements of Russian forces have been decimated by the Ukrainian response."
