Congratulation ricnunes!
Obviously you're the misterious Master of Vinn site, who respected all US Air Force!
Thanks, but who's that (the misterious Master of Vinn site)?US believed that there were a "killer SAM site" and identified it as VN-549.
In reality, there were no such a site.
77th shot down four, 57th shot down three, 93rd shot down two.
No other battalion had more than one.
