Today it is part of the 1st Regiment, Royal Australian Artillery, attached to the 7th Brigade based at Enoggera, Queensland.

Consisting of seven officers and 168 enlisted personnel, under the command of Colonel John Richardson, the battery was re-equipped by the British with six 9-pounder guns and embarked from Sydney in early March.

Most of the major fighting had concluded by the time the battery arrived and, after training, it undertook defensive duties to protect the railway around Handoub, remaining until May when it was withdrawn back to Australia.

[3] The battery's next involvement in conflict came during the Second Boer War, deploying aboard the transport Warrigal on 30 December 1899.

[6][7][8][9] Following Federation, the battery became part of the Royal Australian Artillery Regiment, and consisted of four guns, based in Sydney.

[13] Forming part of the 1st Australian Field Artillery Brigade, the battery was among the first units of the AIF to leave Australia.

[6] Following a period of training and preparation in Egypt with the rest of the AIF, the unit served at Gallipoli, where the brigade supported the British 29th Division around Cape Helles from early May.

After the evacuation of Allied troops from the peninsula in December, the brigade returned to Egypt for reorganisation before deploying to France and Belgium for service on the Western Front commencing in mid-1916.

[16] Following the war, the battery was reconstituted and provided a mounted escort in Sydney during the Prince of Wales visit to Australia in 1920.

[18] Equipped with 75 mm pack howitzers, under the command of Major William Stevenson the 2nd Mountain Battery arrived in New Guinea in September of that year, initially based around Port Moresby with the 3rd Division.

[19][18] In early 1944, the battery moved to Lae and was re-assigned to support the 7th Division in the Finisterre Ranges, where its operations were hampered due to limited transport in the difficult terrain.

On 1 September 1957, the battery detached from the 1st Field Regiment for the Malayan Emergency arriving at Penang in October remaining overseas for two years.

[24] It also later served during the Indonesian Confrontation detaching again to join the 28th Commonwealth Infantry Brigade Group at Terendak Garrison on 21 October 1965.

[24] The battery served in the Vietnam War arriving on 4 July 1971 at the 1st Australian Task Force base at Nui Dat deploying individual forward observers and guns at Nui Dat and several fire support bases to support the 3rd Battalion, Royal Australian Regiment (3 RAR) until November 1971.

[24] In April 2002, the battery deployed to East Timor as part of UNTAET and later UNMISET in non-artillery roles with 3 RAR returning in October 2002.
