Upon mobilization, each of the four peacetime divisions of the Greek Army formed two wartime divisions. The first four of these, which were classified as “active” divisions, bore the numbers of the their peacetime predecessors. Each consisted of nine battalions of infantry, three four-gun machine-gun sections, two or three two-gun machine gun sections, and six batteries of field artillery. The other divisions, which were numbered from five to eight, were characterized as reserve formations. Each of those got three batteries of field artillery, a variable number of infantry battalions, a variable number of two-gun machine gun sections, and, in two cases, two battalions of Evzones.
The Army High Command controlled a reserve of non-divisional units that consisted of six battalions of Evzones, twelve batteries of mountain artillery, three batteries of heavy artillery, and two regiments of cavalry. (The third cavalry regiment of the peacetime army was divided into eight small detachments. Too small for most tactical purposes, the cavalrymen of these detachments were, as a rule, employed as couriers.)
