British Army LAW66's are reloadable, whereas US LAW 66's arent, they are simply disposable
From my army days if i remember correctly it was only practical to carry 1 LAW Launcher in addition to belt gear, bergen and personal weapon.
The actual rocket was stored in a cylindrical container. I suppose it would be possible to carry 2 or 3 in the bergen along with additional equipment when on long range patrols
For a fighting patrol, then all that is carried is weapons and ammo anyway, so i suppose its possible for each soldier in the unit to carry 1 LAW round each, in addition to the support weapons's ammo
The weight of the 66 launcher was a little less than the SLR and SA80, so at a guess was probably about 6 to 8lbs, i have no idea what the rockets weighed
It might be possible to addevent when fired and then setdammage 1 to the LAWLauncher
I have never tried to setdammage to a weapon but it may be possible
As far as using the weapon was concerned, i don't recollect anybody firing a LAW at an armoured target, it was used more on soft skinned and lightly armoured vehicles, buildings and entrenched infantry positions
The Charlie G 80 mm was used for anything bigger, and was a pain in the ass to hump around
