How good a perk is depends completely on your play-style. One Man Army can be good for infinite grenades, ammo and such, because it resets it all, but it is usually frowned upon to use it with different weapons, for an exampe grenade launchers.
silenced scarh -- Perk 1: scavenger or one man army Perk 2: coldblooded or stopping power Perk 3: steady aim or nija FAMAS -- Perk 1: scavenger or one man army Perk 2: stopping power Perk 3: steady aim m16 and ak47 are good as well
I Really recommend ONE MAN ARMY
The perk 'one man army' allows you to switch in between classes while on the battlefield. This helps out when you run out of ammo, require a long range weapon when you have a short range weapon and other advantages. The problem with the 'one man army' perk is that it replaces your secondary weapon.
Either die and chosse diffrent class or use one man army as a perk and switch to your secondary ( which is one man army ) and choose a class.
The best map to get a nuke on is highrise because you can camp on the roof and the gun you need is Primary: ACR Noob Tube Secondary: Nothing Perk 1: One Man Army Pro Perk 2: Cold-blooded Pro Perk 3: Commado Pro Because if you runout of noob tube youcan get your ammo back by using one man army it is really good you should try it

You have to unlock the perk, it is called One Man Army.
one man army is a 3rd perk unlocked at level 56. the perk allows you to change your class at anytime during the game, with a small waiting period, but the perk does take away your secondary weapon. you can also change to the same class you a currently using a get all your ammunition back. what ever class you change to when you die and respawn you respawn with your one man army class and not the class you changed to. if you unclock the perk pro it allows you to swap classes with a smaller waiting period hope thiss helps.
The closest you can get to having infinite ammo without cheating is using the one man army perk(unlocked at level 45), when you are running low simply use one man army.
one man army is a perk that replaces ur secondary but allows u to change any time but have chance to get killed during it though. One man army pro makes it change faster. It also refills ur ammo and equipment or special equipment if u change to the same class.
