ok your point is indeed correct regarding ISO and COIN is not just happening in mindanao,,but the question is ISO and COIN operations in visayas and luzon are far defferent in mindanao sir..visayas iso and coin operation are in need more of huey rather than MG or MD,,they are more on surgical operation small unit operation,,guirela operation not a conventional war operation like in mindanao..i maybee wrong my opinion is base on what i read ,saw and heard,,
they are station in mactan as mactan is in the center..
