(AP) — An Army team is inspecting the cemetery at Fort Riley to verify that all service members buried there are properly identified and commemorated.

The work is part of the Army’s initiative to make proper accounting of 27 cemeteries at 17 sites nationwide by June 30. Nearly 40,000 graves will be reviewed in all.

The work at Fort Riley began last week. The Army team is photographing all grave markers and linking them to a web-based system to help families and visitors locate the graves.

The secretary of the Army issued a directive in 2011 to account for all service members buried at military cemeteries. That order followed the discovery of irregularities at Arlington National Cemetery in Virginia.
