ifresh21, have you stopped beating your wife? (That is a rhetorical question, used to make a point).
Why do military helicopters crash rather than autorotate?
What you did was assume an answer in the phrasing of your question. Some people call this "begging the question," but let's just call it ignorance at work.
On the basis of what evidence do you frame your question?
Here is another way to ask that question.
Do military helicopters crash rather than autorotate?
That is another very ignorant question.
You can autorotate and still end up at the bottom with a difficult landing that results in a crash. This happened to a colleague of mine whose tail rotor quit in a Navy SH-60B.
You can also be over terrain that works against you. You can also cock up the flare and landing. Lots of things can go wrong during a forced autorotation, particularly one involving the loss of tail rotor function.
The other problem with your question would be ...
Are the operating environments identical, or similar enough to make a comparison? This has been addressed by a number of responses to you.
Based on what you have posted, you have neither the background, nor the actual intellectual capacity, nor the curiosity, to explore the question in any depth.
You have a movie made in Hollywood. (?????????????)
WTF?
Do you actually fly helicopters?
