Back on March 17, Joint Base San Antonio logistics personnel installed plexiglass shields in the area surrounding the driver’s seat of vans transporting service members and eligible Department of Defense ID cardholders around JBSA bases. In addition, as of April 1, all 22-passenger surrey buses also had plexiglass installed to shield the drivers. The plexiglass replaces plastic shields, forming a more protective barrier against the spread of COVID-19.
