Hi Blackbird,
I probably won't try your mod (reasons follow below), but I know how frustrating it is to wait for feedback (and not getting much of it), so I thought I'd tell you my impressions of this thread so far.
First, don't be too frustrated if not many people try the mod. The problem is that there are
lots of mods around - I currently count about 170 on my hard drive, and that's gameplay mods only, i.e. graphic mods and maps are excluded. That's just too much to try all of them, even if I wanted to. So I only actually play mods that catch my interest in a special way, that "stick out" from the rest somehow.
I think your mod has the potential to "stick out", as you implemented an interesting idea - you cannot buiild anything, so you have to be very careful not to lose too many units. That's an interesting change of gameplay that has the potential to attract players. However it is a little difficult to find out which specialities your mod has, because that iformation is hidden in several postings and in very long sentences (which I tend to lose track of while reading).
I suggest to make the "specialties" of your mod as easily accessible for a casual reader as possible. Think about it in a way that many readers will glimpse over the first post of your thread, but only for a second or two. In this second you have to give the reader as much information as possible to catch his interest. You can do this by providing clearly ordered, important information in (preferably) clear, short sentences.
On a side note, I also suggest that you reduce your use of exclamation and question marks.

I hope I'm not insulting, I don't intend to. It's just that these heaps of exclamation marks look ... mh, less "professionally", at least for me. Of course that may be only me, and I realize that it's a prejudice. But I think that the impression that you (as a mod maker) give will actually influence how eager people will be to test your mod, and people generally are reluctant to test mods that seem "sloppy", "unprofessional" or "not thought out". Again, I hope I didn't insult you here, I'm not sure how to carry across what exactly I mean and unfortunately English is not my first language, so I sometimes have difficulties to express myself.
So, to sum it up: I suggest a clearer, better presentation of your mod. Look at how other mod makers designed the first posts in their threads, there are many good examples.
Finally, to the mod itself: As I said, the idea of "limited units" sounds very interesting. However I do have other mods on my "playlist", and there are mainly two reasons why your mod will not rank high enough on this list to actually try it.
One is the setting "America vs. Russia". It somehow reminds me to settings that were very common during the times of the cold war: A few "good" high-tech Americans against an abundance of "evil" Russian hordes. I'm not saying that you actually recreated one of those, it's just that your scenario reminds me to them, and I was never very fond of them. That's personal preference of course, other's mileage may (and will) vary.
The other reason is your map. *If* I play something like "US vs. Russia", I'd like to do it on a historical map, or on a map that is "special" in some other way that catches my attention. Your map did not catch my attention, I don't know what's special about it, why you did it this way and how it facilitates the gameplay you have in mind. You obviously *did* put some thought in it (e.g. into the placement of the capital, although I don't fully understand why the capital is not marked as a capital, and why it is placed on a remote island).
However, both of these reasons are personal preferences, so I *do* think that your mod has the potential to attract players. You also seem very eager to get feedback and to learn from it. That's always a good sign.
And, just to say it again, please don't get the impression that I want to paternalize you. After all, you actually completed a mod with an interesting idea, and I didn't, all that I have to show is some unfinished plans and ideas. I honestly admire anyone who has the standing power to design and actually complete a mod.
