CSM Green landed by parachute east of the Rhine on 24 March 1945. Fire round the dropping zone was extremely heavy, and it was largely due to the leadership and drive of this WO that opposition was quickly overcome and the company collected as its rendezvous.
Immediately afterwards the company was directed on a village. A strong and determined enemy force was holding a group of fortified houses on the edge of the village. The attack was checked and success hung in the balance. In this emergency under heavy fire, CSM Green lea a PIAT detachment up to the first house. Having organized covering fire, he led the assault himself on to the house. After capturing it, he then cleared all the remaining houses in succession. The enemy was full of fight but was worsted by the vigour of CSM Green's attack.
This WOs quick and determined action was of the greatest value in clearing a dangerous obstacle and restoring the impetus of the advance. His contempt for danger and eagerness to close with the enemy were an inspiration to the men.
