I went to this museum while I was aboard Ft Eustis for business. I only had about an hour to spare before they closed so I had to rush. I did not get the chance to view the large number of trains, aircraft, etc. that were on display outside. But the inside has a large selection of top-quality uniforms, vehicles, aircraft, dioramas, etc. If you want to read all of the placards and spend time at all of the displays, it will take at least two-three hours. There is no fee for admittance and there is a small gift shop inside. I would recommend checking the museum's website to confirm the operating hours. The only drawback is that it is physically inside the confines of Fort Eustis and the requisite security precautions apply to enter the installation.
