Can anybody explain to me why the excessively heavy M3 Carl Gustav (still not exactly lightweight in its most recent version) is so very popular among anglophones?

Nothing, absolutely nothing in its published specs points at a superiority over the likes of the already phased out LRAC F1 STRIM* and similar weapons.
Is it all about the (recently developed) fancy munitions?

For example, the U.S.Army finally introduced the M3 CG for general infantry and promotes this fact as if they had invented something great, but the marines already had their equivalent already for three decades (an Israeli 70's design).

Sometimes it seems as if the people's capacity to think about weapons and munitions cannot reach beyond a few marketing stars, ignoring more than 90% of what's actually available.
