QUARTERLY TECHNICAL PROGRESS REPORT

1 August - 31 October 1971

1 Collection and general screening of material on personnel incapacitation was completed in August. Theaa activities have since been puraued on a maintenance basis only. Recommendations were prescnted to on August 23rd, as to the utilization of the remaining research effort. Since there appeared to be very little in the way of "brand new" ideas for incapacitation, we suggested that a systems approach be used in which several groups ox families of techniques would be reviewed and reported on in as uniform a format as possible. This approach will ultimately provide a matrix of iniormation by means of which characteristics of different techniques can be compared. Our main emphasis will be on potential applications, physiological considerations and recommendations for future research.

The first substantive report entitled "Electric Curxent as an Agent for Personnel Incapacitaiion, " was completed in October. An outline of the substantive portion of this report is appended. Electric current appears to be a promising means of delivering a wide spectrum of incapacitation to a single individual (or a few individuals). Application of the agent can be well controlled and is reasonably safe under appropriate conditions.

The next subject zrea to be reviewed will be impact and iss application as an incapacitating agent.

Administrative Aspecta

1. A six-months no-cost extension of the project was granted on 20 September 1971. The new completion date is 30 April 1972. This time extension, along with an acceleration of the substantive work of the program will allow csmple tion of the project within the extended tirne limit.
