"35mm Skyshield, a German rotary wing air defense system." 
 WTF is this? "rotary wing"? 
 The system is mostly based on Swiss technology afaik, and the autocannon in question is the 35/1000, a revolver autocannon. 
 Nothing rotary wing - it's "revolver". 
 The project is German, but afaik most tech is from Switzerland (Oerlikon?). 
 It uses the 35mm AHEAD cartridge. 

 Btw, much of the C-RAM and M-THEL stuff won't work well against insensitive munitions. Something like this should be mentioned.
