The date on that image, November 1941, is important. The date is certainly given using the US system (m/d/y).
It was this month that the first fighter-bomber missions were flown in North Africa, by No 80 Squadron, dropping the 40lb fragmentation bombs pictured. They flew support to operation CRUSADER, but what is not mentioned in the propaganda image is that their losses to flak were prohibitive and that they ceased their bombing and strafing attacks on 27th November. This type of loss was precisely how the RAF justified its doctrinal prejudice against such operations.
They had only come about after ACM Sir Arthur Tedder took over as A O C-in-C Middle East in June 1941. He reorganised the RAF's No. 204 Group in the forward area into a separate 'Air Headquarters, Western Desert' and grouped its fighter, light bomber and reconnaissance squadrons into stripped down wings with fewer personnel and increased mobility. In so doing he unwittingly created the RAF's first tactical air force, soon to be known as the Desert Air Force which, in July, came under the command of AV-M Conningham. It was Conningham who developed the communication systems for command and control, with some influence from the work done by A M Barratt and the RAF's Army Co-operation Command, that would eventually underpin the successful use of air power at the battlefront in 1944/45.
