Army personnel will face compulsory redundancies when the MoD begins its latest round of job cuts, reports The Daily Telegraph.
The paper says commanding officers will be informed today about which areas will be hit in the third of four "tranches" of cuts.
Personnel will be given around two months to apply for voluntary redundancies, but some compulsory redundancies will also be made.
Those made reduntant will be informed of their fate in June, says the paper.
