Envelope with special cancellation «Hawks. 411th Separate Unmanned Systems Brigade»

The history of the 411th Separate Unmanned Systems Brigade “Hawks” began in 2022 with the establishment of the first separate unmanned aerial systems battalion within Ukraine’s Defense Forces. Over the course of four years, the unit evolved into a separate brigade of the Unmanned Systems Forces of the Armed Forces of Ukraine.

“Hawks” have carried out combat missions in the Kharkiv, Donetsk, Zaporizhzhia and Kherson regions, as well as in the Kursk region.

Today, the brigade combines aerial reconnaissance, analytics and strike unmanned systems into a single cycle — from detecting a target to engaging and destroying it. At the same time, “Hawks” develop their own technological solutions. Among them is the Vezha analytical module, integrated into the Delta system, which transforms battlefield data into information for rapid decision-making.

One of the brigade’s key areas of operation is countering enemy aerial targets, including Shahed-type attack UAVs.

In this way, “Hawks” combine people, data and unmanned technologies into a single system — from detecting an aerial or ground target to its destruction.

The envelope features artwork based on a quote from a poem by Ukrainian poet Taras Shevchenko — “And there will be no enemy on the renewed land…” — and bears the “Trident” postmark with a special cancellation “Hawks. 411th Separate Unmanned Systems Brigade”.

Issued as part of the “Personalized Stamp” project.
