ISIS on the offensive in Iraq

[Seamus Fermanagh]

All things that are not armored with significant amounts of armor are vulnerable to MG fire.

MG fire is more difficult to put on target based on the target's speed. Some aircraft are actually faster than MG bullets, making targeting a real challenge.

So yes, propeller-driven craft are more vulnerable to MG etc. fire than are fast flying jets and the like.

But you should also remember just how difficult it is to shoot ANY moving target, much less one going 400+kph.

Ground based MG rounds expended versus kills is quite a high number. Remember that these numbers are likely optimistic given reportage at the time.

In effect, yes you lose a bird every now and then, but ground based MG and small arms fire is not a serious deterrent to most aircraft and by themselves are not capable of stopping a multiple aircraft attack.
