https://translate.google.com/#view=home&op=translate&sl=en&tl=ru&text=screened screen or shield: screened is another translation of shielded and shielded gets close to a shield used in battle (medieval knights) so it is indeed up-armoured as John writes.
Further hints about the naming can be had from Trumpeters kit nr 00357:
with the "nickname" Ehkranami. The Russian language might have loaned the ekran from the French écran which means screen or shield (as in armour shield used by a knight, also the actual coat of arms).
A shield used in a sword fight has another name, transcribed as "shchit" (щит) which I think is pronounced as the first sound of shield (sh) immediately followed by chit (sh-chit). Don't even think about trying it after a few beers .... bystanders will think that you are drunk ....
