The Army has a message for its retirees: Uncle Sam wants you to help fight the novel coronavirus.

A message sent by Defense Finance and Accounting Services, which processes and dispenses retiree pay, asked troops who had previously served in specific health care specialties to consider “re-joining the team” to address the current pandemic crisis. It’s signed by Lt. Gen. Thomas Seamands, deputy chief of staff for U.S. Army Personnel, G-1.

“We need to hear from you STAT!” reads the message, obtained by Military.com.
