The original purposes of this research were to determine peacekeeping operations nature and characteristics and to review and evaluate the ABCA concept and US Army doctrine. During the literature review, doctrine was evaluated as inadequate resulting in a new purpose to enhance doctrinal development. The case study method, with a structural-functional approach incorporating comparative analysis, was employed to examine three UN operations: UNEF 1 (Egypt), Cyprus, UNEF 2. The UNEF 2 was judged the best example of a peacekeeping operation from a military perspective. The conclusions were that peacekeeping operations were political actions by military organizations for behavior control purposes; consent is the key to peacekeeping; the ABCA concept is adequate with modification for doctrinal development; and US Army doctrine can be adapted, with modification, to peacekeeping.
