The Army is now reimbursing troops who buy commercial plane tickets for travel home on Rest and Recuperation from Iraq and Afghanistan. Payment may be authorized through a travel voucher, said an Army spokesperson, and must include receipts. Reimbursements for fares already paid are retroactive only to Dec. 19, when the reimbursement program began, and do not extend to the beginning of the R&R program, which started on September 25. All service members and Defense Department civilian employees deployed on 12-month orders within the two theaters become eligible for the R&R between their third and 11th month in the theater. The 15 days of R&R are chargeable as annual leave.
