About 2 hours.
You could spend time watching each video at each area. They are all amazing stories and some told by the people who the scene is all about! If you did that plus watch the movie and take time to read and explore each setting, it could take 3+ hours. If you want to skim through and "see" each thing then 35-45 minutes. But give yourself as much time as you can! There are such heroic sacrifices individuals made that shaped battles and saved countless lives. The stories are told here. The volunteer I met was in one of the groups featured at the museum. Talk to people. They are there for a reason as well. God bells you all
We were there about 1 1/2 hours but we hurried a little at the end because we had young kids.
It really depends how long you take. If you like to watch the videos at each exhibit. Ir you can generally walk thru pretty fast. But it's a pretty awesome place and if you can take your time through it.
30 mins - 1 hour I'd say, it's not very big.
