Pentagon officials say an Army colonel who wrote an internal email suggesting photos of attractive women should be avoided in promotional materials has stepped down from her duties involving a gender study.

Army spokesman George Wright said Friday that Colonel Lynnette Arnhart had agreed to step aside from leading the gender integration study.

According to Politico, which first reported the email’s contents, Arnhart stated that “average-looking women” should be used in Army materials used to attract women for combat roles.

Arnhart is stationed at Fort Leavenworth as part of the Army’s Training and Doctrine Command Analysis Center.

In addition, Wright said Colonel Christian Kubik, a public affairs officer, was suspended for his involvement in the email.

Messages seeking comment from Arnhart and Kubik weren’t immediately returned.
