Type in whatever case works for you, of course. I appreciate your service for our country.

It always strikes me as odd when people bring up performance on the battlefield in these threads. How many of our rifles are going to be used in battle rolled around in the muck? It is really irrelevant. An AR chambered in the 7.62 can function as well as one in 5.56. This makes it useful for a range toy, hunting, self defense, plinking out in desert, or whatever. To ask what use is one is akin to asking what use is any firearm.

One thing for sure is an AR in any caliber is likely to be far more accurate and easy to shoot than an AK. An AK just doesn't fit a lot of people very well. I shoot my son's and to me they feel like they were designed for something other than the human species. But people like them and that is great.
