The latest round of cuts to the Army will be announced this morning.
The Ministry of Defence will set out the number of posts it will cut from the service in order to reduce the size of the Army by a fifth.
Previous reviews have concluded the Army should be reduced in size to a strength of 82,000 personnel.
It is thought around 4,800 posts will be axed today. Those who have not applied for redundancy will be forced to leave. They will be informed by their commanding officers.
The MoD maintains that any member of the Army on operation, about to deploy, or recovering from deployment have been exempted from this round.
These job losses are not connected to the current arguments over the next Spending Review (2015/16) which will be announced on 26 June.
Those negotiations are still on going and the Ministry of Defence is one of the departments which has yet to settle its budget for that year.
The Royal Navy and RAF were cut by 5,000 each at the time of the 2010 Strategic Defence Review. Those posts have already been cut and the Navy and RAF are not involved in today's redundancies.
