Captain Mick Battle entering 5RAR's Command Post. Captain Battle had just taken over as Intelligence Officer from Captain Tim Britten who became Second in Command of D Company.

This was Operation Twickenham where 5RAR went into ambush positions around the Nui Thi Vai Mountain.

A major seven-hour battle ensured in this mountainous terrain of the northern valley of Nui Thi Vai when Major Reg Sutton's A Company was met by an aggressive, well armed force from D67 Battalion located high in the caves and amongst the rocky outcrops.

The operation closed with the enemy driven from his bases.
