A swimsuit calendar featuring British models that was reportedly shot in US army property without proper authorization prompted an investigation by US military.

The investigation was launched after the release of video footage showing the girls firing rifles on the Utah National Guard base in Draper. More specifically, the footage shows the models in sexy bikinis posing with weapons, holding bazookas and riding in tanks.
The Utah National Guard confirmed to the Daily Mirror that it has launched the inquiry into the provocative calendar that may have been filmed using its facilities, equipment and personnel without authorization.
The “Hot Shots” calendar raises money for British military charity Help for Heroes, an organization that helps provide financial support to wounded troops and their families.
