Quali sono le differenze tra l' H1 e l' Humvee?

Here is a list of differences between the HMMWV's (High-Mobility Multi-Wheeled Vehicle) and Hummers The body styles are very similar, however the soft-top is different for the military then civilian and the military hard doors are different then the civilian full hard doors and the civilian half soft / hard doors. (Military Vehicle Variants Listed at the end)

This list is generalized and is not meant to be a comparison from year to year of the Hummers and / or Humvees. Both have changed in options and architecture since their first conception (1985 for the Humvee and 1992 for the Hummer).
Here are a few differences regarding crash test comparisons of H1s and '80's era HMMWVs:

ALL H1's have;

A hood restraint system (helps prevents the hood from intruding into your space and completely ruining your day)

A collapsible steering column (helps your ribs continue to protect your heart, lungs, and other important stuff)

A windshield glass retention system (helps keep your head on your shoulders)

A 3 Pt. restraint (seat belt) system (helps keep your head, etc. from spoiling the appearance of your vehicle's interior surfaces)

A T-Case restraint system (helps keep you from getting too HOT by reducing the likelihood of the T-Case and rear prop splitting open the fuel tank)

This is why AM General (the contracted manufacturer) and our Government (the specifier and original owner of ex-mil. HMMWVs) is none to happy to see 80's vintage HMMWVs in private hands and in use On-highway and Off-road?
The largest difference between the two is the electrical system
