Defence malus of helis vs bombers not displayed properly?

In description if helis it is stated weak defence vs other aircraft, however in the help/unit list it doesnt show anything else than -2 vs stealth
In my DS experience when my helis are attacked by bombers while carrying marines, marines defend first !!
so I suppose there is a -2 def malus vs bombers, but it is not displayed
thoughts?
Cheers

It was removed as a buff to ds, the descriptions of a lot of stuff are outdated.

How come marines defend first then when they have 3 def compared to 5 for helis?
