There are so many way to engage the Ex Service Personnel. They can be utilised by giving some simple in house training to do some routine type work. Office Clerical work, Accounting work, Stores management, Supervisory work, etc which needs minimal skill level. For higher end also you can get (For Middle level Management class) Commissioned Officers, who can tactfully handle the task.
Especially I felt that, if we compare with raw civil public, the ex-servicemen can perform better way and accomplish the task well in time.
