Kammler was assigned to oversee the V-2 Program on August 8th 1944, not March 1995. Kammler had previously overseen the V-3 programn in 1943 maybe earlier, and previously wanted to move the entire rocketry project from Dornberger's and Von Braun's post at Peenemunde to an underground facility at Mittelwerk, which ironically would have saved the nazi's from losing the entire operation as keeping Peenemunde operational led to leaked intel to Polish intelligience and subsequent bombings by USA and Soviet troops, and finally a soviet invasion in May 1945 at which point most of the facility was in pieces.

I tell you what, if Kammler were recruited by Operation Paperclip I certainly wouldn't defend that fucker. According to a former OSS Operative Donald W. Richardson, he says Hans Kammler was supposedly "interned at a place of maximum security, with no hope, no mercy and without seeing the light of day until he hanged himself".
