Latvian and Canadian forces are currently conducting a large-scale military exercise focused on the integration of ground drones, marking a significant shift in remote warfare from the air to the land. The exercise, known as Crystal Arrow 2026, is taking place at the Sēlija training site, a remote forested area chosen to prevent specialized electronic warfare jamming from affecting civilian populations.
Approximately 2,500 troops, including Canadians, and 500 pieces of equipment are participating in the war games, which are scheduled to run until May 15. The Latvian Brigade is leading the operation alongside a Canadian-led multinational brigade.
Integrating Ground Robotics
The exercise focuses on remotely piloted ground vehicles, ranging from small four-wheelers to larger systems resembling oversized shopping carts. These unmanned systems are being tested for a variety of missions, including intelligence gathering, kinetic effects against enemies, resupply operations, and casualty evacuations.
Lt.-Col. Andris Bruveris, commander of the Second Mechanized Infantry Battalion—known as the Iron Battalion—emphasized the necessity of this technology. He stated that unmanned systems are the future because they are “cheaper than people’s lives,” noting that drones can conduct reconnaissance without sending personnel behind enemy lines.
However, other leaders maintain a more cautious view. Canadian Lt.-Col. Dan Richel, deputy commander of the Latvian Brigade, described uncrewed aerial systems (UAS) and uncrewed ground vehicles (UGV) as complementary systems rather than replacements for front-line soldiers.
Political Crisis and Drone Vulnerability
The push for automation comes amid a political crisis in Latvia following a mistaken Ukrainian aerial drone strike on a Latvian oil storage depot last week. The incident led to the resignation of Defence Minister Andris Sprūds over the weekend.
The country’s prime minister requested Sprūds’s resignation, citing that anti-drone systems were not deployed quickly enough. While no one was injured, the event highlighted the risks of drone manipulation; Ukraine’s foreign minister claimed that Russian electronic warfare interference deliberately diverted two strike drones intended for Russia into Latvian territory.
Russia has denied responsibility for the incursion and has not acknowledged jamming the drones. In response to the event, both Latvia and Lithuania have called on NATO to increase air defenses in the region.
The Future of Autonomous Warfare
The incident in Latvia serves as a catalyst for NATO nations to accelerate their defenses against uncrewed systems. In response to these evolving threats, the Canadian military has begun deploying counter-drone systems at its major airbases and naval ports.
Claudio Palestini, Head of NATO’s innovation and technology adoption section, stated that the alliance is conducting tests and trials to improve the efficiency of the interceptor network to build resilience across all domains.
Mubin Shiekh of the tech company CTRL suggests that the world is moving toward a “new reality of autonomous warfare.” This evolution may eventually include not only aerial and ground drones but also unmanned submersible vehicles.
While Lt.-Col. Dan Richel suggests that unmanned systems may one day perform independent operations, the current focus remains on fitting these technologies into rigid military command structures. The pace of development on the battlefield suggests that technical achievements in electronic warfare may be short-lived as counter-measures evolve.
Frequently Asked Questions
What is the purpose of the Crystal Arrow 2026 exercise?
The exercise involves Latvian and Canadian troops testing the use of ground drones for intelligence, kinetic effects, resupply operations, and casualty evacuations.
Why did the Latvian defence minister resign?
Andris Sprūds resigned after the prime minister determined that anti-drone systems were not deployed fast enough to prevent two Ukrainian strike drones from hitting an oil storage depot.
How is Canada responding to the threat of uncrewed systems?
The Canadian military has started deploying counter-drone systems at its major naval ports and airbases as part of a security upgrade.
Do you believe autonomous ground vehicles will eventually replace human soldiers in high-risk reconnaissance missions?
