a result of vigorous supervisory emphasis and follow-up by the maintenance section of the brigade. This policy, implemented initially in August 1968, was a carry-over from the preceding year. Also as in 1968, the CMMI team continued to as an instruction activity, making frequent liaison visits for the purpose of instructing equipment users, maintenance personnel, and commanders on materiel management and preventive maintenance techniques. The results obtained by this approach were very encouraging: CMMI scores for 1969 improved considerably over those of the previous year. The average CMMI score in 1968 was below 70 percent, a failing score; the average for 1969 was a greatly improved 78 percent. Of the 123 units inspected, 79 percent were rated satisfactory while 21 percent were unsatisfactory. Two force reductions occurred during the calendar year, one during the period June through August 1969, code-named Keystone Eagle, and the other during the period October through December, code-named Keystone Cardinal. Together, these reductions totaled 65,000 troops. The general supply and maintenance section was responsible for the logistical planning and execution of Keystone Eagle and Cardinal which entailed the following: Identifying and making provisions for the redistribution and retrograde of excess assets, such as stocks, equipment and materiel, generated as a result of the redeployments/inactivations Turning over and/or acquiring facilities/real estate to satisfy changes in mission assignments brought about by force reductions Developing and distributing, as appropriate, the necessary instructions required to execute the logistical aspects of the operation Although instructions were given out initially in a rather piecemeal fashion because of policy and procedural changes emanating from USARV, a very workable plan was developed by the time that Keystone Cardinal got underway. Published as Annex F to Brigade Operations Plan 183-69, it proved effective in guiding, monitoring, and controlling redeployment actions. Two important lessons that were learned from the force reductions were: Logistical planning must be done at all levels as far in advance of the date of redeployment/inactivation as possible. There must be a continuing effort among all units to identify and eliminate excess During the first half of 1969, the policy on new construction in Vietnam was liberal, just as it had been in 1968; and there were sufficient funds available to satisfy most medical construction exigencies as well as to satisfy brigade upgrade plans. Starting in June, however, USARV curtailed all but the most essential construction. The impact that this had on the
