AH-64A Apache 2 questios

[Headhunter88]

Hi. 2 more questions, this time strictly about AH-64A Apache version:
1. Which model is more real Task Force Normandy configuration??

or this one

??
2. Why some of AH-64A's have on the top left and right avionics sponson black square flat element's (i suppose that they are anti slip carpets just like those on wings).
Is it a early/late modification for whole fleet or only some of AH-64A'a had them.
Example without them:
