DynCorp International is moving its headquarters to Falls Church from Texas, as it focuses on securing more government work. DynCorp's local workforce will double, from 50 to about 100, as part of the move. DynCorp has built a business providing personal security and training police forces in Iraq and Afghanistan, as well as mine removal services, aircraft and equipment maintenance. It is just the latest stop for the $2 billion company. In 2002, it was bought by Computer Sciences, leaving its Reston headquarters. Two years later, Computer Sciences sold part of the business to a private equity firm, which took the firm public this year.
