Now that's realistic IOC dates! Maybe a tad conservative at that
OK; I'll se myself out...

The 1970s-80s evolution of your helicopter force sounds sensible and similar to that of some IRL forces. Developing a light-attack concept on the Mi-2 and then transitioning to the Mi-24 is good, but might have happened earlier, if helicopters were a local priority (see below).
The bit about the initial batch of Hinds not being fitted for (or delivered with) ATGMs and the rest carrying AT-3s is a nice touch too, though one assumes that a competent air force would have had them re-wired as soon as more modern models became available.

Still, I'm a bit surprised that you don't mention earlier helicopters. For a modern and geographically dispersed nation such as your CCCN, a dedicated transport helicopter like the Mi-8 should have been a priority acquisition at least 10 years earlier. Not to mention you taking about "more modern Mi-4 utility choppers" when the Mi-4 is the granddaddy of them all and should have been the first transport helo to enter CCCN service in the 1960s. Or is that bit just a typo and you were thinking of another model? Right know what you describe is akin to replacing Jet Rangers with Chichasaws in time for Operation Desert Storm...
Also, evolving from Mi-4 to Mi-8 to rocket-armed Mi-8TV and then branching out to Mi-24s would be more typical of Soviet-inspired doctrine, where the highlight is on assault landings and fire support, not tank-hunting. Not to say that your evolution is impossible, just atypical. Out of the Soviet allies I can think of, only Poland went this way, as well as Yugoslavia to an extent.

Of course, if you're preparing another post detailing the 1950s-70s history of the CCCN helicopter force, please disregard all of the above - except the Mi-4 part, of course.

Side note: are the non-Comintern relations of the CCCN so bad that they can't score helicopters from non-Soviet sources at all? An earlier side-order of some Alouettes or AB-47s or Westland Scouts would be another plausible start for a light-helicopter force, see e.g. Romania or Yugoslavia.

I'd furthermore suggest, in addition to what Lambda has already said, for your initial Mi-24s, the ones not wired for ATGMs, you might consider the Mi-24A as opposed to the D version, which was more of a pure gunship. Hind-A, with its big greenhouse canopy is delightfully retro, and a good stepping stone to the more advanced D model. They'd probably also be available rather cheap, too.

Ok I will swap out the Mi-4 for the Mi-8. I'm somewhat uninitiated when it comes to helictopers, you'll have to forgive me.

I intend to have relations with non-Comintern nations to start improving around the early 90's, after the development of a small nuclear arsenal leads to the signing of several nuclear treaties, and the collapse of the Soviet Union leads to the CCCN seeking help from western nations and transitioning more towards a left wing democracy rather than a communist dictatorship. Kind of like china.

I will also take this opportunity to say that I am NOT a communist! This is just an AU and I don't sympathize with the Soviet Union or any of the Comintern states. I am rather right-wing when it comes to these sorts of things.

Nice to see this. First thing first, the image appears to be shrunken down by Photobucket, and doesn't show at full scale.
If you can't cut it down to 1000 pixels width without losing part of the ship, I suggest finding another image host.
Once you can show this ship in its original size, I'll be happy to discuss its design!

I would suggest that your stern may get a little "damp" in any kind of weather and at any kind of speed old chap
