Ukrainian civilians receive weapons training at a shooting range in Brno, Czech Republic, 27 March 2022. The project by CS Solutions Group, which provides Ukrainians with free weapons training, is partly funded by a public collection. The money goes towards ammunition. The rest of the cost goes to the shooting range. The external instructors, who do not charge anything for their work, are also a big help. They started the fundraiser on February 28 and had their first takers as early as March 1. About 120 people have already gone through the training, some have come repeatedly. According to organizer Petra Rupova, there is indeed awareness of the training among Ukrainians in the Czech Republic, as evidenced by the continuing interest. (Photo by Martin Divisek/EPA/EFE)
