hopefully correct info above. To achieve and maintain a level of fitness which meets the needs of the employment theatre requires time, funding and support across the full spectrum (not Capt. Scarletts spectrum).
A possible way ahead would be to practice operational conditions regularly, perhaps in a series of build up scenarios with a 'building block' approach, them meld smaller entities together to increase the effectiveness across units, then combined scenarios across units, then force sized events with realistic input.
We used to call them microval, minival, taceval etc.
*to include all personnel, but especially those 'undeployables'
