The Freedom of the Borough of Douglas is to be conferred on an Army regiment that recruits in the Isle of Man.
The honour will be given to the 12th Regiment Royal Artillery at a ceremony in the town later this month.
The regiment recruits heavily in Lancashire, Cumbria and the Isle of Man and counts Manxmen among its members.
The ceremony will be held outside the town hall in Ridgeway Street, before the regiment marches to the war memorial, where wreaths will be laid.
The ceremony will involve the Mayor of Douglas, Councillor Ritchie McNicholl, and the commanding officer of the regiment.
Douglas is the only council on the Isle of Man empowered to confer the honorary Freedom of the Borough.
It is the highest honour Douglas Borough Council can bestow and was first exercised in 1924 when the Right Honourable the Earl of Derby was honoured in recognition of his war service and his part in creating the Douglas war memorial.
Manx Olympic cyclist Mark Cavendish was given the award in 2008, in recognition of his outstanding achievements in international cycling.
The surviving members of the Bee Gees were made freemen of their home borough of Douglas last year.
