Although highly beneficial to the survival and combat effectiveness of US troops in Southeast Asia, the Jungle Operations Committee remained fairly low profile throughout the early 1960s. However as American involvement in Southeast Asia increased, so did the importance and utilization of the JOC. Extensive positive feedback about the value of instruction was quickly brought to the attention of LTG Creighton Abrams, the U.S. Army Vice Chief of Staff. Soon the Department of the Army (DA) increased the quota of trainees for the JOC, and agreed to increase instructors and funds late in 1967. In addition to conducting course after action reviews, the JOC sent questionnaires to officers and NCOs that deployed to Vietnam about 90 days after they had been in country; this questionnaire asked for a reappraisal of course curriculum based on their experiences. The commentary received was very positive overall, but valuable suggestions were made that led to modifications in the course. In October 1965 a team from the USARSO G3 visited a jungle perations course being taught in Hawaii. The POI was similar to the Panama jungle operations course, but the Hawaii course included a cordon and search of a mock Vietnamese village; this was added to the Panamanian course. This program of cadre/instructor self-critique and rotational unit after-action reviews (with the goal of constantly refining the Jungle Operations Course) continued until the school was closed in 1999.
