They may have used the inside of the training complex to prepare for what they thought they were going to encounter on the various levels given the intelligence they received and built up. I do, however, agree with the opening poster because I highly doubt the American's would decimate a fairly new training complex when they could use countless other look-a-likes of Osama Bin Laden's residence in the Afghanistan towns which are not well populated. Wherever the Navy Seals trained they done a great job.
