what a great movie. tons of action, tons of movie stars. lots of explosions and action!it has a decent storyline abt a debacle in africa. must of had a billion extras in this movie. but anyways, storyline abt a mission goof up that cost the US rangers and delta force quite a bit of time to evacuate their forces that were stranded in hostile territory. realistic fight scenes and a glimpse into how the terrain and fighting might have looked like.
