Turnbull announcement became a joke....but for his companion cadets. for professor it was a great shock..
the Turnbull did this because he wanted to take revenge from professor because professor has messed up with him by interrupting him in lecture....
the platoon officer has asked Turnbull to choose one for permanent kitchen incharge. then he threw a bombshell of humour by saying ''i think that professor is the perfect man for the job..'' by saying this he took his revenge....
hope it helped.please mark it as brainliest.
