To add regarding Eisenhower: as a captain he commanded the tank training unit at Camp Colt, on the battlefield of Gettysburg National Military Park, on the field where Pickett made his famous charge. Soldiers were welcome in local churches where they also could have some off-base relaxation and recreation (my church was one that welcomed the soldiers). Captain Eisenhower and his family lived in a home adjacent to the Gettysburg College Campus, near the location of an office (now the admissions office) he used after his presidency. He and Mamie bought a working farm in Gettysburg in 1950 and retired there after his presidency. The farm is now part of the Gettysburg National Military Park.
I believe Paul's Triplex brought the troops to Gettysburg and also delivered the Renault FT-17 tanks used for training the soldiers.
