what are the main vulnerability points of "hardened" helos like the apache?

let's assume the threat is small arms fire up to moderate caliber
shells - no major hardware. is it:
-main rotor and associated machinery?
-turbines?
-tail rotor and associated machinery?
-something else?

is there one or a couple areas disproportionately at risk? or are
they pretty much evenly vulnerable?

Those who know won't tell for pretty
obvious reasons.

Hardened to 25 mm cab and 35 mm in critical areas.

Judging from what I read here,http://www.dtic.mil/ndia/aircraft/6.pdf
the folks involved in this discipline would like to have their efforts
more in the forefront. Recent events suggest survivability is a back
burner issue until bad things happen.
Here are some more links:

The finer points of "Survivability" "Susceptability" and
"Vulnerabilty" could well use some greater understanding and attention
all up and down the food chain.
Specific to helicopters each of these newsletters has some articles
that you may find ineteresting(these are slow to load):
