There is some misunderstanding I think.
Back when US consulates has run a lot of programs around Russia. These people were visiting schools, colleges. If you liked it you could go to consulate proper for their classes, seminars etc.
It was a long time ago. I wouldn’t recomend one to visit US consulate now. At the time they taught about God, rule of law, checks and ballances, free enterprise etc.
Today, they would probably push for muslim outreach, abortion and gay pride.
Which Russian president(s) was your military service under, did you do Army, or Navy, or what?
