The "caskets" were part of DOD project to increase the number of military cemeteries. Remember, this was post 2001 when the war on terror was ramping up. The "caskets" were vault liners. The cemeteries were constructed so that a plot wouldn't need to be dug immediately before each funeral. There have been at least 26 military cemeteries built since 2001.
