How 0400 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 0400 is hour 04, minute 00: 4:00 a.m.
Said aloud it is "zero four 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.
