Berlin Schönholzer Soviet memorial (#0402)

обнажите головы! This first line must be a colloquial way and even in English comes out weird -- we don't tell people to 'take off your hat' ('bare your head')

здесь покоятся вечным сном советские воины Roughly, 'here lies our Soviet warriors'

герои великой отечественной воины Heroes of the great patriotic war
1941-1945

они отдали свои жизни за ваше счасть They gave your lives for our welfare (happiness)

I was a Russian linguist in the U.S. military in the 1960's, which resulted in a very poor Russian, but at least some sense of how to translate.
