KPAF

North Korea's Air Force is in shambles. It's newest plane was some 25 MiG-29A/UBs back in the 80s. No one knows if they are still flying though. But in March 2003 it was confirmd they were still flying after they intercepted a USAF Recon plane. In the first sentence of the article it says:

The North Korean air force is short of fuel and many of its planes are decades old, no match for the modern firepower of the U.S. military. http://http://www.globalsecurity.org/org/news/2003/030305-dprk-intercept01.htm

I think we can say that the KPAF doesn't get the right amount of flying time and lacks the flight hours of other nations. Now let's say a guerilla war is waged in North Korea. The MiG-29A/UBs couldn't carry guided bombs, and it's doubtful that North Korea has many. The only plane that the KPAF can truly launch a strike with is the Su-24 Frogfoot, a 60's era plane that can't match the payload of today's multi-role fighters. The thing that really concerns countries is that even though the MiG-29A/UB cannot not carry guided bombs, it does have a good payload and chemical and biological weapons won't have to be guided in order for it to effect Seoul. Biological and Chemical weapons also work well in counter-insurgency. So they must be protected! The key is to sabotaging railways and cut off the fuel that is going to the KPAF so after a month or so they'll be dry.
