"The void left by this tragedy will never be filled" - these are the words from the family of 22-year-old Craig Roderick, who was killed on Sunday while serving in Afghanistan.
Born in Cardiff, Craig Roderick was a member of the 1st Battalion Welsh Guards. He started training at Catterick on 22 February 2009 before later joining the Welsh Guards in the September of that year.
Mr Roderick's parents Mike and Sadie, two sisters Katie and Lucinda Emily, stepbrother Jay, grandmother Margaret, and girlfriend Zoe.
They paid this tribute to the guardsmen:
A second Cardiff man, Leonard Perran Thomas who served with The Royal Corps of Signals also died alongside Guardsman Roderick.
Mr Thomas leaves behind his mother, partner Rachel, and younger brother Tristan.
The Ministry of Defence first confirmed the deaths of three soldiers on Monday.
Fellow Welsh Guard Apete Saunikalou Ratumaiyale Tuisovurua from Fiji also died in the incident.
The MoD said on 1 July all three were part of a patrol to a checkpoint to help organise a meeting with the Afghan National Civil Order Police. Having completed their task and on leaving the compound, they were said to be attacked by a man in an Afghan police uniform. They died from their injuries.
