Hi Deb,
It's unfortunate that you don't seem to know Peter's patronymic (that's your father's first name + special ending, an important part of any Russian name). It's also a pity that you don't know the name of the village that his family is from: Arkhangelsk is a big city, and it's in a pretty big region - lot's of towns and villages there, lot's of different names.
The good thing, though, is that you know for sure when he was born and that he was drafted (unless he changed his date of birth and/or last name when starting a new life - not uncommon)/ The documents must be in the Central Military archive of Russia in Podolsk (TSAMO, ЦАМО in Russian). It is, unfortunately, a pretty challenging archive to work with, so I would advise hiring a Russian-speaking professional genealogist who worked with that archive before to get results.
Then there are several very useful sites for finding Soviet citizens who participated in WWII. I tried looking Peter up, but I can't seem to find the right one (though I did just a quick search, definitely try looking him up yourself). Try here

The correct spelling of that name in Russian is Пётр Худяков (or Петр Худяков, as it is commonly printed).
Good luck!
