A flag-lowering ceremony has taken place at Weeton Barracks to mark the disbandment of the 2nd Battalion, The Mercian Regiment.
The unit, raised in 2007, saw action in Iraq and Afghanistan and subsequently deployed troops on operations in Mali, Ukraine, South Sudan, and Estonia.
Speaking at 2 MERCIAN's Lancashire base, the battalion's Commanding Officer, Lieutenant Colonel Richard Grover MBE, said the event was a "sad time for all of us".
The commanding officer added: "No-one wants to be part of an amalgamation, but we have been determined not to be defined by it over the last 15 months since the news broke.
"We have maintained battalion cohesion, focus, and our fighting spirit to the end.
"We have ensured that the finish has been marked with a mixture of celebration and dignity; celebrating everything that the battalion has achieved in its 15 years of existence, and remembering with dignity the fallen from the operational tours served.
"Stand Firm, Strike Hard."

In July, the regiment's Colonel-in-Chief, the Prince of Wales, made a final visit to the unit, during which he met with around 80 members of the battalion and their families.
Prince Charles used the visit to thank the battalion for its service and handed out Platinum Jubilee medals to selected soldiers.
Most of the battalion's members are transferring to other units, while some have taken the amalgamation as an opportunity to return to civilian life.
