Dear fellow citizens,
It is an honor for me that this campaign for drone hunters — or “interceptors,” as we soldiers call them — carries the nickname.
My nickname “Charlie” has been with me for almost my entire military life. Friends and colleagues have called me that for decades, and that’s why this drone — designed to hunt down and destroy Russian attack drones — is simply called CHARLIE ONE.
I am proud and grateful that it will help to protect vulnerable people, especially families with children in Ukraine. And not only in Ukraine. Every drone shot down above Ukraine is a drone that never reaches the Czech Republic — thanks to your help.
My cordial thanks go to each one of you who contributes, whether with a small donation or a regular monthly gift.
And I invite you to read the story we have lived together over the past weeks and months as we prepared this campaign.
With respect,
Karel Řehka
Army General, Chief of the General Staff of the Czech Armed Forces

CHARLIE ONE PROJECT
The CHARLIE ONE project focuses on supporting systems that enable the early detection and interception of aerial threats before they impact populated areas.
These systems are designed for rapid deployment in the field and help reduce the risk of damage to civilian buildings, infrastructure, and human lives.
For security and tactical reasons, we do not disclose details about the products or their exact technical parameters. The cooperating organizations use proven suppliers who are able to deliver these technologies even in the current extremely challenging security situation.
KEY REQUIRED FEATURES
Quick preparation and deployment.
Ability to operate at night and under difficult operating conditions.
Accurate tracking and elimination of attacking drones targeting civilian infrastructure.
Less expensive than the destroyed system or damage caused by the intervention.
Operation requires only a small mobile team of operators.
WHY THESE MEANS ARE IMPORTANT
Attacks by unmanned aerial vehicles often target energy infrastructure, transportation, or residential areas. Any system that can stop such a threat while it is still in the air can prevent extensive damage and protect civilian lives.
According to the experience of defenders in affected areas, modern protection measures can significantly increase the likelihood that an attack will be stopped before it reaches its target.
Each additional system increases the chance that the threat will end in the air – not over the city.
HOW YOUR HELP HELPS
Thanks to the support of donors, it is possible to contribute to:
providing means of protection designed to protect the civilian population and infrastructure
technical components needed for their long-term deployment
service and operational facilities that enable their safe use in the field
Support for the project goes to organizations and partners that use these resources to protect the population in areas exposed to attacks.
SUCCESS OF DEPLOYMENT
When used, these resources are about 80% effective. The exact rate of interception depends on weather conditions and enemy tactics, but each additional CHARLIE ONE device significantly increases the chance that an attack will be intercepted in the air before reaching its target, rather than in a residential area.
HOW MUCH DOES IT COST?
The price of individual systems and their configuration varies depending on the type of technology and equipment.
For effective deployment, a complete operational set for one team is usually required, which includes the systems themselves, spare components, batteries, service equipment, and other technical support.
For example, the production of one protective drone at the expected production numbers costs approximately CZK 23,000. One ground station is required for every 50 to 100 drones. The cost of this station increases the price of one drone by approximately CZK 2,000.
Every contribution helps to increase the ability to protect civilians in areas that are regularly exposed to attacks.

Why We
Do This
We refuse to stand by while Russia destroys the lives of women, children, and ordinary civilians. We will not pretend this war does not concern us.
Russia openly labels the Czech Republic an enemy and deploys weapons capable of reaching deep into Europe. It is our responsibility to help to stop attacks that could one day threaten us directly.
Families with small children spend nights in garages and basements, terrorized by repeated drone attacks. Deadly machines strike residential homes, schools, hospitals — without warning and without rules.
The only effective defense is to stop the drones before they reach populated areas. Every drone shot down means saved lives, less fear, and greater safety — for Ukraine and for Europe.
Ukraine. Night. Air-raid sirens scream.
Families rush into underground shelters as a swarm of Russian suicide and bomb-carrying drones heads for their city. CHARLIE ONE is a defensive interceptor designed to destroy these machines before they reach residential zones — before they strike families and burn their futures to the ground.
Help us equip Ukrainian defenders with technology that saves lives. Every intercept means safety for civilians. Help those who protect all of us on the front line.
Stories We Must Not Forget
Anastasia Masliy, 19 — killed together with her mother
Kind-hearted, honest, always smiling. That’s how classmates from Kyiv’s Líder Lyceum remember Anastasia. She had dreams like any young person. In the night of October 26, 2025, a Russian drone hit the apartment building where she and her mother lived. They hid in the bathroom — and never made it out.

Antonina Zaichenko, 38 — mother killed together with her children
She left Kyiv to keep her children safe. On October 22, 2025, a Russian drone struck the village where she had taken refuge. The explosion levelled the house within seconds. No one survived.

Nikol Haranska, 5 — killed in a night attack on Kyiv
A major drone strike killed at least three people, including five-year-old Nikol. Fires spread across residential buildings; 147 drones were launched in one night. Most were intercepted — but not all.

Who Organizes the Campaign?
The face of CHARLIE ONE is General Karel Řehka, who lends his moral authority to ensure the campaign’s professionalism and focus on protecting civilians.
Behind the project stands Skupina D (Group D), which has already delivered thousands of drones and related equipment to Ukraine — worth over 263 million CZK — all thanks to donors.
You can also support Group D’s non-profit work through the operational account: 4846290003/5500
Historical Legacy
The organization’s name honours Special Group D, established in 1941 by the Czechoslovak Ministry of National Defense in exile. Its intelligence officers selected and trained paratroopers for missions in Nazi-occupied territory.

How It Works
Choose Your Donation
The selection of the most appropriate means according to current needs and the security situation is ensured by a partner non-governmental organization in Ukraine in cooperation with the end user.
This model also reflects the fact that the Ukrainian embassy stopped accepting funds for the purchase of aid at the end of 2025.
We Secure the Equipment
Our organisation does not handle purchasing or logistics. Transparency is ensured by a handover protocol from the partner organisation and confirmation from the end user.
Transparent Reporting
You will receive transparent feedback. We will continuously publish reports on the acquisition of funds and their transfer on social media and our website.
Upon your request, we will issue a donation receipt for tax purposes.
Facts
Security
100% of the funds go directly to partners in Ukraine. They will use the protective equipment where it is currently most needed.
Transparency
Transparency and control are key for us. The promoter of the CHARLIE ONE campaign – Group D is undergoing an ongoing forensic audit by a major US auditing firm.
The price has been reduced based on the need for increased production and the generosity of our donors.
FAQ
As part of the CHARLIE ONE campaign, interceptors are not sent from the Czech Republic to Ukraine. They are purchased directly by a partner organization in Ukraine from a local manufacturer. Group D is responsible for organizing the campaign and collecting funds, while the partner organization is responsible for selection, purchase, and logistics. The entire process is carried out in accordance with the applicable legal framework.
CHARLIE ONE is not a public collection under the Public Collections Act, therefore the funds raised cannot be used to cover the costs of running the campaign. 100% of the donated funds will be used to purchase protective equipment.
The campaign is run by volunteers. In the future, we plan to partially finance the campaign from the sale of merchandise and support from friends and supporters of Skupina D.
