text_A: In 1948, Egypt's army was able to put a maximum of around 40,000 men into the field, 80% of its military-age male population being too out of shape for military service and its embryonic logistics system being limited in its ability to support ground forces deployed beyond its borders. Initially, an expeditionary force of 10,000 men was sent to Palestine under the command of Maj. Gen. Ahmed Ali al-Mwawi. This force consisted of five infantry battalions, one armoured battalion equipped with British Light Tank Mk VI and Matilda tanks, one battalion of sixteen 25-pounder guns, a battalion of eight 6-pounder guns and one medium-machine-gun battalion with supporting troops.
text_B: Would leaders of Egypt's army in 1948 likely blame most of their lack of troops on the number of citizens available to serve in the army?
YES.
