This is an old family photo. Can anybody identify the uniforms in this picture?
My family was from Russia/Ukraine/Belarus.
Any other info would be cool -- about the medals?
Most likely they are Imperial Russian army uniforms. The giveaway is the double-headed eagle on the the buckle of the standing soldier. https://en.m.wikipedia.org/wiki/Coat_of_arms_of_Russia
The white tunics are characteristic of soldiers who fought for Russia during the 1905 war with Japan. In 1907 uniforms were changed to a khaki type so the photograph is likely dated before that year. https://www.rbth.com/arts/2015/03/03/the_last_hurrah_of_the_russian_imperial_uniform_41727
The standing soldier has a double breasted tunic with a single stripe on his shoulder. The single stripe indicates an enlisted soldier of the second rank. https://en.m.wikipedia.org/wiki/Imperial_Russian_Army
@justCal has identified one of the medals as an 'excellence in shooting' medal. https://www.emedals.com/europe/russia/badges/a-russian-imperial-shooting-excellence-badge-grade-two
