During this exercise, the LCD and the 937th conducted detailed planning for a deliberate crossing of the Yesong River in Korea, but once again did not execute a deliberate crossing.
To support a deliberate crossing of the Yesong, III Corps allocated the 937th Engineer Group two corps combat-engineer battalions (one wheeled and one mechanized) and four bridge companies (one assault-float-bridge company and three multirole bridge companies) to the 1CD.
A key element of both the synchronization drill and the rehearsal was the development of a battlefield-operating-system checklist (Figure 4, page 32) to ensure that the conditions for a deliberate crossing were set.
