The AEF operated with what was called “The Square Division” containing four infantry regiments of thirty-six hundred men each. Two of these regiments would make up an infantry brigade, giving each division two brigades of infantry. In addition to the infantry regiments there were twenty-four other units in each division giving a total complement of twenty-eight thousand men. This was two to three times the size of a British, French and German division. These numbers were rarely achieved as can be seen in the chart below.

NOTES [1] Numbers reflect those present on given date; does not include absentees. At any given time a large percentage of the Division's officers and N.C.O.s were away from their units attending courses and schools. One of the reasons for the massive casualites suffered by the division during the Hindenburg attack was the large number of experienced leaders who were away for additional schooling at the time of the attack
[2] This number probably reflects transfers to other units or duties rather than casualties
[3] The 52nd. Field Artillery Brigade did not serve in action with the 27th Division. For a more accurate picture of the Division's strength the numbers for the FA should be subtracted from the Division's total strength.
