Comando Supremo: german snipers and sharpshooters research - Comando Supremo

Hi, I'm currently researching about german snipers and sharpshooters. The reason for this is that there is hardly anything written about the subject and what's available leaves a lot of unanswered questions. Many snipers didn't survive capture, few soldiers were as hated by the enemy as the sniper.
Hopefully I will get to interview two former german snipers. I have discovered some important things that are different between german and soviet snipers and this will be interesting to develop and see if my thesis about the russian sniper tactics superiority is true.

The real problem with this project is the difficulty in gathering information, there will soon be published a book in german about waffen ss snipers by bernard jocher which I hope will be useful. I've tried to get 'Im Auge des Jägers' but so for with no sucess. However, this research has meant that I've stumbled across a big amount of interesting information.

If anyone has any information to share please email me or post a reply here. Any type of contribution will be welcomed.
