From the 1960s, most Corps officers were tertiary educated with many at the post-graduate level in either mapping or computer disciplines and military command and staff training. This was the key to understanding the potential, application and implementation of emerging technologies and techniques across all aspects of Corps capability. Corps soldier training was both broad within a trade, across Corps trades and specific to specialised equipment with military training for various levels of leadership. Officers and soldiers posted outside Corps positions were highly regarded. Until the 1970s the Corps sponsored and trained soldiers in trades other than the mapping related trades essential to its operations. These included drivers, storemen and clerks. After some rationalisation the Corps retained career and training responsibility for all mapping related trades, and also photographers (non-public relations), illustrators and projectionists who were posted mainly to training institutions and headquarters.
