Deletion of Josef Allerberger

Comment: though a slightly uncomfortable one: He's the second-most successful (recorded) German sniper of WW2 (behind Matthäus Hetzenauer) with 257 confirmed kills, and according to John Plaster in ''https://books.google.com.au/books?id=qIHKAwAAQBAJ History of Sniping and Sharpshooting'', has the only first-person account of a WWII German sniper. The original German language version was apparently significantly longer (and used pseudonym Franz Karner). Interviewed in 1967 in Austrian military journal :de:Truppendienst_(Zeitschrift)|Truppendienst per https://books.google.com.au/books?id=8g_PBQAAQBAJ&pg=PT87 this - (?partially?) http://forum.axishistory.com/viewtopic.php?t=10324 transcribed here. Referenced in multiple books, eg https://books.google.com.au/books?id=4LZGCgAAQBAJ&pg=PT114 Shooter's Bible Guide to Tactical Firearms, https://books.google.com.au/books?id=8g_PBQAAQBAJ Sniper in Action, https://books.google.com.au/books?id=-mkh931pIugC Out of Nowhere: A History of the Military Sniper. The discomfort arises from so much of the sourcing ultimately coming back to Wacker, which is rather , and it being unlikely that there are many better, more-reliable sources
