Report from UK media "Russian soldiers given church-blessed Warhammer-inspired seals to ‘keep them safe’" (https://archive.ph/hCRqb)
These seem to come from a company called Ratnik Technical, I've found reports on bits of Reddit that people have been doing this in a more adhoc manner for at least a year but I find it interesting that these are (a) coming out of a company and (b) getting blessed by priests. An interesting mix of things.
