How 1100 is written and said

AR 25-50, para. 1-26: "Military time will be expressed in a group of four digits, from 0001 to 2400, based on the 24–hour clock system. The first two digits represent the hour after midnight and the last two digits represent the minutes." So 1100 is hour 11, minute 00: 11:00 a.m.

Said aloud it is "eleven hundred". On paper the same paragraph says "The word "hours" will not be used in conjunction with military time," and that military time is used for memorandums while civilian time is used in letters.
