Ex Soviet countries got different legacy from their parent the Big Soviet Union. To list some many Soviet armaments, some were lucky enough to get their hands on missiles and atomic stuff, then all the infrastructure etc etc.
And the compulsory army service is also the thing those countries have from Soviet Union. Like in good old times young boys of 18 and till 27 years old have to take their bodies to the army recruitment point and get their service for one year or more or.. get jailed or at least can’t get a job etc etc.
Then when they get in the army there are some legacies in there from Soviet times too. One of the most interesting facts about Red Army is that there were no socks allowed until some very recent times (2008 or something) or maybe even later. The thing that they used instead of socks were pieces of cloths that were called “portianka” and had to be wrapped around the feet each time young soldier had to put on his boots (everyday).
It takes it roots from 19th century and was totally compulsory for every soldier of Red Army in 21st century.
And this can be continued on and on, better let’s see some photos how they recruit to Army in Ukraine these days. Looks like nothing has changed from Communistic times. Same old tradition to stand pants down before a group of lady doctors for every young man in the country.
