It's hard to bring 'iron' proves or screenfy this one (due to it's hard to get serious response form support) but...

I feel special forces are loosing hp with or without a fight, after air strike, or by touching enemy provinces, by fighting with 'grounded' air units - those are probably not the reasons but that is how it looks. They are not dying but they are seriously damaged before main strike and this is annoying.

I suspect:
- hp status delay (which shows hp fully recovered but it's not in fact),
- rush turned on by default(without speed effect),
- 'grounded' air units make defensive damage to helicopter (sf air strike).

Other:
- i know about random factor, terrain features etc.,
- problem repeats,
- i didn't rush them,
- i didn't retreat,
- there were no airstrikes, missiles etc. I've missed or something,
- I've searched the forum for similar threads.

Did anyone else had the same problem?

Noob question then.

Are mountains/jungle/desert damage my units?

( If so, any details how this works - hp per hour or per province, airstrike also?
Interesting. )

So, I'm really sorry for that one. I don't like to bother someone with such tiny things.
