WAR VETERAN FUNERAL EXPENSES

My stepfather, Retired Chief Storekeeper Eugene Segee, passed away on August 1st at the age of 86.  He served in the Air Force, Marines and the Navy.  He retired from the Navy in 1979.  He was in both the Korean War and Vietnam War. He always told my mom he didn't need life insurance because the Navy would pay it all.  They don't pay for his cremation.  I'm told Mom can be reimbursed for some of the cost but that it takes a while.   I'm helping my mom with his cremation and with the military funeral.  I'm also helping her raise the money to pick up his ashes.  Any help would greatly appreciated.
