A good commando doesnt need many bullets to be effective. I often have more than half my ammo at the end of a wave, even wave 10. The team has to be really bad for me to nearly run empty.
Check out that vid of a wave 10 on Hell on Earth. I do have a great team though, they do not let Fleshpounds and Scrakes get anywhere close.

I do not play commando very often, so thats one of the few I have with half decent mando' kills.
And for a personal point of view, in regard to overall usefulness AS A TEAM, I place commando ahead of zerker, medic and firebug.
- Firebug : Unless the player is good, which is rare, Firebug can be very annoying by raging/unstunning scrakes and limiting the sharpshooter / commando headshot ability.
- Medic : unless the team is bad a medic is not really necessary as good players often heal each other. But its still very useful to block stray Fleshpounds and scrakes before they do too much damage.
- zerker : I really love zerking, its great to hold on your own or even kite. But I got to admit thats not really fitting the cooperative spirit of the game. Even if the zerk stays near the group and take zeds head on, they most often get in the way of everybody else behind and block incoming shots. Though, I got to say that in some cases zerkers have their use; their damage absorption coupled with a medic make a great wall to block a small entrance xD
Yes, that video certainly had a long shootingrange for a commando!
