How to do a satchel charge jump in call of duty 5 on wii?

the person above me is talking about the other versions, not the wii version, so he doesn't know about it. to satchel jump, what i do is just stand on top of the satchel charge, then press B, and as soon as you press it, jump. you have to have the flak jacket perk or the juggernaut perk on to do this, or else you will suicide.
