ranks on shoulders look a lot better then those in front. army has a reason for displaying the ranks in front of the chest rather then on shoulders. according to them enemy snippers easily target the officer who is putting the rank on the shoulders. but in air force they don't face such situation.so it's better to keep the ranks on the shoulders. but it is a different story that PAF has always remained obsessed with the USAF trying to follow them in every thing so they will follow them in uniform as well. it was quite a shame when some radar operators were wearing the american and pakistani flag in the insignia of some air defence unit. the first time i noticed that was in the documentary about the paf academy and americans were humiliating us regularly in those days. salala incident and the OBL raid and we putting their flags on our uniform. air force doesn't need a new uniform . the standard blue uniform should be used for office work and the cover all for the flying/maintenance/ field work. it's always funny to see the paf officers sitting in some desert during exercises wearing the blue uniform with all the medals and stuff and with oxford pattern black shoes.
