“Airfield repair during use of facility – As often happens in Vietnam tactical necessity dictates immediate heavy usage of an abandoned or deteriorated runway. In order to insure continued use during the emergency, and to upgrade the field for greater capacity, an engineer repair force is airlifted to the assault field. Military police must keep unnecessary traffic off the runway.” – Lieutenant Colonel John R. Manning, “Operational Report – Lessons Learned, Headquarters, 168th Engineer Combat Battalion, Period Ending 31 July 1967 ”
