Q'UARTE,RLY TECHNICAL PROGRESS REPORT I August - 31 October 1971 Collection and general screening of materiil on personnel incapacitation was completed in August. Thede acEiviLida hive since been pa:raued on a n-iain- tenance basis only. Recommendations w@--re presented to on August 23rd, 2 af; to the utilization of the remaining research effort. Sinr-e theye appeared to be very little in the way of "brand new" ideas for incapacitation, we sugges- ted that a systems approach be used in which several grovps or farnili.!s of techniques would be reviewed and reported an in as uniforrn a form- at as possible. This approach will ultimately provide a matrix of iriforrnation by 2 means of which characteristics of different techniques can be compared. Our ma-in-ern.phasis will be on potential applications, physiological considerations and recommendations for future research. The first substant-'.Ve report entitled "Electric Current as an Agent for Person- nel Incapacitaaon, It was completed in October. An outline of the substantive lportiozi of this report is appende2d. Electric current appears to be a promising means of delivering a wide spectrum of incapacitation to a single individual (or a few ind:@Viduals). Application of the agent can be well controlled and is reasonably safe u--ider appropriate conditions. The ne:xt subject z@rea to be revie,med will be impact and i4s application as an incapacitating agent. Administr6ative Aspects 1. A six-months no-cost extension of the project was granted on ZO September 1971. The new cornpletion date is 30 April 1972. This time extension, along with an acceleration of the substantive work of the program will allow compl@- tion of the project within the extended time limit. 0 0 E.-:pcnditures to date: Quarter Climulative AMOLIrlt of total Arnount of total Nov. 1970-Jan. 1971 $ 1.2 $ 1.2 Feb. - Apr. 19 7 1 1 14.4 15.6 May-Jul. 1971 7.7 23.3 Aug.-Oct. 1971 22.3 45.6 2- E:LECTRIC CURRENT AS AN AGENT FOR PERSONNEL INCAPACITATION 1.
