I've been using 1.0 since its release and have been attacked on just about every patrol. I find that its often when they're in pairs (hurricane) usually both of them will strafe me. I'm nearly always out of ammo when returning for a refill or ending a mission (AI hits them more often than I do

). I've recently started a new campaign and still have the VIIA so I'm not far at all currently.
I've also seen a fair share that will pass on by not bothering to attack... its always random if they'll attack you or not.
Edit\ Here's a shot I recently posted in the screenshot thread of me getting hammered.
