212th MP Company - Long Binh Detachment The Army was evaluating the new concept of phasing out their Sentry Dog mission and replacing it with the new Patrol Dog concept. Two Patrol Dogs and handlers were received by the Battalion for an evaluation of their capabilities in South Vietnam. One NCO of the 212th MP Company and a graduate of the Sentry Dog School, were detailed to evaluate them during their four-phase deployment.
Phase-1 was conducted from 7-28 November, and consisted of in-country acclimation of both dog and handler in unsuitable conditions. Both the acclimation period and the most unsuitable perimeter post evaluations were conducted at Long Binh Post, and the Vinh Long Army Airfield. It was determined that the Patrol Dog could be as effective on perimeter post duty as the Sentry Dog. In addition the Patrol Dog possessed more tolerance to vehicles and noises in the perimeter post area, better adaptability to conditions in the immediate area, and greater amenability to handler control.
Phase-II was conducted from 30 November-28 December, and consisted of area post and building searches conducted at the Class I (explosives) yard of Long Binh Post. During the latter part of phase-I and during phase-II, the Patrol Dog worked without a leash during the majority of the evaluation. The Patrol Dogs were tested on their ability to run building searches, and were found to be extremely effective.
Phase-III was conducted from 30 December 1970-19 January 1971, and consisted mainly of vehicle patrol, point control, and gate guard. It was found that the presence of a Patrol Dog within an MP vehicle added a psychological advantage, in that those personnel under apprehension and riding in the vehicle presented no problems to the driver. The presence of a Patrol Dog in a tense situation increased the confidence of the MP, and the presence at the scene of a disturbance with a lot of onlookers resulted in the crowd dispersing rather quickly when they saw the dog.
Phase-IV was conducted from 21 January-5 February 1971, and consisted of an overall evaluation of Phases I, II and III. During the final evaluation conclusions were drawn that: overall performance and effectiveness of the Patrol Dog is far greater than that of the Sentry Dog; the Sentry Dog has the capability of performing only one mission while the Patrol Dog has the capability to perform several missions; and that they could easily be substituted for Sentry Dogs and enable a military police company to perform the dual role of law enforcement and security.
To verify their evaluation they assigned one team to roving patrol during the period of 11 February-8 March 1971, and found it readily adjusted to riding in a motor vehicle. Two additional Patrol Dog teams were employed at FSB Vandergrifth (I Corps Tactical Zone) during the period 12 March-1 April, and tested at physical security.
Although the overall performance of both Patrol Dog Teams were rated as gratifying, the outgoing artillery, mortar rounds and incoming indirect fire rounds, appeared to make one of the K9’s nervous, which indicated that more gun-fire training is necessary. Both of the Patrol Dog Teams were utilized on motorized patrols at Long Binh Post under OPCON of the Provost Marshal.
