Nice post, but like someone said before on one of your other guides, you should make less guides, and focus more on the quality and depth of one or two guides.
In this I personally reckon you should add gametypes easiest (demolition, domination), different methods, (using danger close to hugely assist with killstreaks, either by switching out with OMA or whatever), excellent spots on particular maps to camp out for a few kills then switch, and you didn't include claymores! In all honesty, if I go for a nuke, scav + claymores are essential to me surviving, plus a few extra kills.
Take this advice as constructive, not flaming

Thanks for the post again
