chopper gunner smart people
in mw2 you need to get 10 nukes to get the emblem, i have got 13 nukes camping on ground war, demolition or domination with a noob tube (grenade launcher) with one man army pro, danger close pro and commando pro. the killstreaks should be harriers, chopper gunner and nuke. it does get hard once you come out of the chopper gunner with 5 kills off.
get 2500 headshots

Get 25 AC-130s
There is no rhino emblem. Unless you are talking about the Ghost emblem, in that case it would be reaching 10th Prestige.

10000 headshots with snipers
The hyena...You have to get 50 kills with a RPG.
