I have the 3rd and 4th editions. There was a HUGE jump in content from 3 to 4, but not much of a jump from 4 to 5. More like a minor update.
I'm holding out to see if 6 is better.
Like anything, you are FAR better off buying a specialized book for the country in question (e.g. Babckbone of the Whermacht, Crown Jewels, Argentine Mauser Rifles: 1871-1959, etc.)
MMROTW is more of an identification reference than anything else.
I have Backbone of the Whermacht. Unfortunately it needs a heavy update, as it is rife with errors.
