-------------------- JEST BELOW --------------------
Montana, since you are a slow thinker that doesn't comprehend complicated things easily (not a personal attack, right?), I will once more try to explain the issue of paratroopers to you in a way that you may be able to understand (not an insinuated personal attack, right?). I understand that it will be hard for you to follow my wise insights into the historical use of paratroopers, but maybe, if you try very hard, you might be able to drink from my flawless source of wisdom. (not a personal attack, right?)
-------------------- END JEST --------------------
1. American, British and German airborne troops did capture and hold ground on multiple occasions during WW2;
Agreed. But the maximum size captured was incomparably small to a CoW-sized province. Plus, there was always a relief plan, they would never launch an unsupported attack. The "we're always surrounded" phrase says it all.
2. once on the ground, airborne infantry were and are no less effective than conventional infantry units of comparable size in holding ground against enemy counter-attack; and
Agreed, they would hold those little stamps of territory they captured on the first day. They would never attack from those small bridgeheads though.
3. your argument about a single unit capturing a province of 100,000 square km is specious because no comparably-sized, single real world unit of 800 to 1,500 men could do that, either, so you are attempting to hold a new airborne infantry regiment to a different standard than any other existing in-game unit.
None of the units in CoW is accurately represented. For example, a mega-succesful empire on the 100p map, which has conquered a continent or even more, usually has (a lot?) less than 200 units. Lets say half of those are land army, so no more than 100 land units. If we would calculate 5 regiments per division (for an infantry division, 3x infantry rgt, 1x artillery rgt, 1x all kinds of support units), that's less than 20 divisions to hold a continent. For comparison, that is about 40% of the size of Army Group Center during Barbarossa ALONE. I don't have figures handy for the entire German army at that time (they roughly held "one continent"), but I remember a figure between 200 and 300 divisions. So: our CoW "regiment of infantry" is actually the equivalent of more than two divisions. And yes, forces of that size did launch independent offensives for territory.
But that's not even the main point. We shouldn't think of "a regiment of infantry" or even of "two division of infantry", we should think of "a unit of infantry". And "a unit of infantry" DID take 10,000 sq.kilometer of ground on countless occasions in WW2, while "a unit of paratroopers" NEVER did. Which is why I think that "a unit of paratroopers" shouldn't be able to take provinces in the game that we all love so much.
To me, there is not a single line of bias, flawed logic, or inaccurate historical fact in the above. In fact, if you fail to see my line of reasoning, I would doubt your mental health (not a personal attack, right?). But of course, I may be wrong. Please tell me where, but please DON'T fall back to those same three arguments above, because they're obviously invalid. Don't be a broken record, try something new.
And just for the record, I am NOT against paratroopers in CoW, I'm just against CONQUERING paratroopers! They would be a support unit, reducing the movement penalty of moving through enemy territory - for REGULAR troops accompanying them.
