The 104th Field Battery, Royal Regiment of Australian Artillery had its beginnings in Moascar, a small town near Ismalia, Egypt in March 1916. At this time the Battery was raised as part of the general expansion of divisional artillery prior to the AIF going to France. In the ensuing 63 years, the battery has been disbanded and re-raised four times. Notwithstanding, the battery has seen active service in France and South Vietnam, and has been a Howitzer battery, a Locating battery, a Medium battery and a Field battery, the role in which it was last employed before its most recent disbandment.

Since being raised as a part of 22 Howitzer Brigade, it has served with 4th Field Artillery Brigade, 1st Field Regiment, 12th Field Regiment and 8th /12th Medium Regiment and now 1st Field Regiment at Gallipoli Barracks, Enoggera, Queensland.

104 Field Battery completed two tours of South Vietnam as part of 12 Field Regiment, in support of 4 RAR/NZ. It had the distinction of being the last artillery unit to serve there, departing for Australia in December 1971.
