"From July 1943 to June 1944 he was responsible for the detailed preparation of the special order of 1 Corps, the recommendations for special scales and types of vehicles equipment and stores, and their distribution to formations. This was a major task. When planning started in January he was responsible for the preparation of all the landing tables and staff tables etc of the Corps which had four divisions under command with various Corps and Army Troops amounting to over 140,000 men.

Throughout all this time his judgement remained sound and by his determination and common sense he surmounted all difficulties smoothly and with great efficiency. That everything occurred as planned (and there were NO mistakes) is very largely due to his untiring efforts."

"Brigadier Mullen has now filled the appointment of Brigadier, GS of the MO Directorate for two years. In this capacity, a key position in the War Office, he has to act both as the Deputy to the Director and also head of the coordinating section. His responsibilities cover every aspect of General Staff Policy and his tenure of office has included the Suez Crisis of 1956 and the recent disturbed situation in the Middle East. During these periods, considerable extra responsibility has fallen upon his shoulders, more perhaps than any other officer of his rank in the War Office. He has had to work long hours. The smooth running of the War Office staff machine during the last few months has been directly due to his example, his ability and his own efforts for which he deserves great credit and is worthy of very special recognition."
