content: If you are a military buff with a particular interest in US Naval Special Warfare, chances are you will enjoy this set. I managed to record (on my VCR, at the risk of dating myself) 2 of these Discovery channel programs when they aired 12 years ago, and it's great to finally have them on disc. This is an excellent glimpse into the world of the SEALs- probably the closest a filmaker will be able to get, especially these days. There is quite a bit of shared footage between the shows, but each episode has its own theme so there is always new information. The Hellweek episode is particularly fun- I think I enjoy it just as much, if not more, than the Class 234 Hellweek episode- though I bet that I'm the only one who feels that way! Instructor Kelm is the man, by the way.There's a bit of extra footage on all 4 to fill in the gaps and make them each 50 mins.All in all, for this price it is beyond worth it for a buff to add it to his/her collection.
