PETERSBURG, Va. (AP) -- Fort Lee is raising awareness of suicide prevention.
The Petersburg base participated Thursday in an Army-wide day devoted to suicide prevention.
Fort Lee's "stand down" also focused on sexual assault and harassment prevention.
The day's events and training began with more than 10,000 soldiers and other military personnel participating in a 2-mile run.
Fort Lee has been investigating whether four deaths this year were suicides. If confirmed, it would represent a sharp increase in the number of suicides.
The Army is the largest of the services and it has the highest number of suicides. The Pentagon has been struggling with a spike in the number of self-inflicted deaths this year.
