And I don't know if it still in game, but IMO there should be a risk (percentage of "chance") that an airborne mission - because of unappropriate weather conditions or because there is strong units in the landing province- turns into a fiasco and the unit may be reduce to very low statistics both in number of soldiers and org/strength... Now in 1.3 it is really to easy with paratroopers...
I agree with the comment on Paratroopers. Initial Leadership cost should not be the fix. The real issue is that when dropped, they should not as powerfull as a true "inf" division & have limited AT capacity & have limited supplies.
Compared to a regular Inf Div, a static paratrooper division should be more powerful for SA/Defence, but weaker on the HA front (less effective, but more mobile AT weapons).
When dropped, the strength & org of an actual Para division is reduced dramatically (units scattered, equip lost during the attack). Thus potential fixes should be:
1) reducing org of unit when dropped
2) reducing HA of Airborne unit over Inf. reduce it further when dropped.
3) reduce supplies of Airborne unit when dropped. (30 days now. Probably should be more like 5-7 days. Thus forcing resupply by Tpt if in combat...)
I think Airborne should:
1) Cost much more leadership (who are the elites after all)
2) When dropped, be unable to move or attack or occupy provinces until relieved by a land supply connection
3) Defensive supplies should last probably 3 days. After a week with no relief, it should probably be destroyed by even a militia force.
4) When the province that has been attacked with airborne troops is eventually occupied by other friendly land forces, then the occupiers should get a substantial bonus to surviving infrastructure (so a level 10 port would be captured at level 5-8 or so, and so on for the other)
5) Engineers should also have a similar effect on province capture, but at a reduced level (and defending engineers should be able to counter this effect)
That would allow paratroopers to be used not to capture or attack independently, but to support an attack by capturing key infrastructures (bridges, air ports, ports etc) relatively intact.
