The British Army's Irish Guards have celebrated St Patrick’s Day in traditional style with a parade and shamrock presentation in central London.
The parade took place on Sunday, two days before the calendar event.
In attendance were past and present members of 'The Micks', while members of the only reservist guards, D Company, London Rifles, also took part in proceedings.
Warrant Officer Class 1 Ryan Robertson of the Irish Guards, Regimental Sergeant Major of the London Regiment, said: "For the Irish Guards, as the only Irish Guards regiment in the British Army, this holds a particular importance for us.
"It’s our day, the 17 March is always St Patrick's Day and we always hold it as close to, if not on, that day."
At Wellington Barracks, the Chief of the General Staff Sir Mark Carleton-Smith watched on as his wife, Lady Carleton-Smith, began the distribution of fresh shamrocks to each guardsman which is then attached to the headdress.
After the traditional presentation of shamrock, the parade continued to Horse Guards Parade, allowing personnel to remember the fallen and those still serving in Iraq.
WO1 Robertson acknowledged many involved in the parade will have lost friends and colleagues, and it is "nice to come together and be able to remember those" who have died.
Soon, many in attendance at the St Patrick's Day celebrations will be swapping their ceremonial duties for UN peacekeeping mission, Operation Trenton, in South Sudan.
