Reserve Citizen Airmen and civilian personnel from Youngstown Air Reserve Station pose for a group photo on Oct. 11, 2019, in front of a witness tree at Gettysburg National Military Park. A witness tree is a tree that was alive when the Battle of Gettysburg occurred. Witness trees at Gettysburg are marked with small metal tags for visitors to identity the tree as one that was present for the three-day battle that took place in July 1863.
