The Mid-Michigan Chapter of the Red Cross is hosting its annual Battle of the Badges Blood Drive.
It happened Monday at the East Lansing Marriott.
Donors give blood and then vote for their favorite police or fire department. The winning department gets bragging rights.
"You can save three lives with one blood donation," said Todd Kulman, the Red Cross communications manager.
Kulman said they were hoping to collect 125 units of blood at Monday's drive, which can potentially save 375 lives.
