Unfortunately I can't help you with camping spots as I have same exact problem as you, ~5 kills, and naded/killed in some way, shape, or form. So i'd like some expert camping spots too! lol.
But to get nukes, on small map, just run n' gun, surprisingly it works good for me, you'd think camping is safer but this works flawlessly for me..
Class:
Primary: UMP45 w/ silencer
Secondary: 1887 akimbos, pp2000, or something you can actually kill with for a backup when/if you run out of ammo.
Equipment: Semtex
Special: Flash (never use them)
Perk1: Marathon (Pro)
Perk2: Stopping Power (Pro)
Perk3: Steady Aim (Pro)
Death Streak: Doesn't matter cause you shouldn't die that many times when going for a nuke
best of luck, and hopefully someone can post some useful camping spots.
