Activision can not reset you.
1. You can prestige each of your 10 soldiers again, then reset.
2. You can ask a modder in game to prestige you, then reset.
3. You can create a different account, that will probably just get hacked.
4. You can switch to PS4 Ghosts.
Be warned, on PS3, some modders will initiate a game setting that will insta-kick & insta-derank you if you so much as randomly join their lobby.
