A Welsh Guardsman shot dead in Afghanistan has been described as a "formidably talented team commander" by a senior officer.
Lance Corporal Lee Thomas Davies from 1st Battalion Welsh Guards and Royal Air Force airman Corporal Brent John McCarthy died in Helmand province.
Tributes have been paid to L/Cpl Davies, 27, who was born in Carmarthen and grew up in Cardigan.
The number of UK military deaths in Afghanistan since 2001 is now 414.
The Ministry of Defence (MoD) said the two men, who were deployed as part of a police advisory team, provided security near a base in southern Afghanistan.
Their deaths came as Afghanistan announced plans to take over security in the Nahr-e-Saraj area where UK forces operate.
L/Cpl Davies's family were described as devastated by their loss.
He joined the Army in 2009 and was promoted in December last year.
The commanding officer of the 1st Battalion Welsh Guards, Lt Col Dino Bossi, said: "To have made such a profound impact so early in his Army career speaks volumes about the quality of the man we have lost.
"On duty he was a consummate professional, whether 'strutting his stuff' on public duties in London or on operations here in Afghanistan. It is in Afghanistan that the depths of his talents became obvious to all.
"He was a formidably talented team commander, in his element in this complex and unforgiving environment.
"The Welsh Guards have lost a man of inestimable promise, a fine Guardsman who lived and breathed the values and standards of the Foot Guards.
"He will be missed by all of us. Our thoughts and sympathies go out to his family."
Maj Julian Salusbury, commander of 2 company Welsh Guards, described L/Cpl Davies as "committed, capable and thoroughly dependable".
"He could not have been more suited to helping the Afghan police achieve a better, safer life for the Helmandi people," Maj Salusbury said.
Defence Secretary Philip Hammond said: "Both servicemen were performing an invaluable role, training and mentoring Afghan police, helping to ensure that Afghanistan will never again be a place from which international terrorists can launch attacks on our society.
"Their sacrifice will not be in vain and we will never forget them."
