This museum boasts of being the largest collection of military artifacts in the nation and it's easy to see why. It is 3+ floors in size and boasts many different galleries including the history of West Point, the history of US Wars, the evolution of worldwide conflict, and small & large scale weaponry. The curators of the museum did a nice job of organizing their artifacts by topic and keeping the information in each gallery at a reasonable level. Even if you have been to many other historical military museums, there are still some unique objects here that you won't find anywhere else: Napoleon's swords, Washington's pistols, the binoculars Warren used at Gettysburg, and objects taken from Herman Goering when he was captured by the Allies.
You could easily spend 3-5 hours here depending on your interest level and how many other military museums you have visited. Unfortunately, the large scale weaponry gallery was closed the day I visited (blamed on sequester cuts) so if there is something you are really interested in, you might want to call ahead. I would also make sure to GPS the location or print Google Maps directions before you come... it's a little confusing to reach. Overall, though, highly recommended.
