Soldiers from the 1st Battalion the Yorkshire Regiment are parading through York to mark their homecoming from Afghanistan.
It is the latest in a series of parades around the region with marches already being held in Leeds, Bradford and East Yorkshire.
York mayor Keith Hyman said it would be a celebration of their service.
Earlier this month the government announced the regiment's 2nd Battalion would be lost as part of defence cuts.
The Yorkshire Regiment currently consists of three full-time battalions.
The cuts mean the 2nd Battalion, formerly the Green Howards, will be absorbed into the rest of regiment in autumn 2013.
In March, five soldiers from 3 Battalion, the Yorkshire Regiment, were killed when a bomb exploded under their vehicle in Helmand province.
