Javelin CANNOT fire multiple missiles from one launcher at once.........
Dude, have you ever used a Javelin before?
A Javelin missile system were made up of 2 parts. A CLU (Control Launch Unit) and a Missile Housing. Missile housing house 1 single missile and it is disposable. which mean once that missile is expanded, the housing is to be discarded. CLU have to plug into a housing before you can launch a Javelin missile, without either, you can't launch anything.
1 CLU can only be plug in 1 housing at any time, you can take the CLU off and plug it in another Missile Housing and fire that housing, CLU can be reused, Missile Housing cannot.
And no, you cannot port a CLU in 2 missiles. You have to fire the one you plug in, and then take it off and put it on another and fire it.
