Anyone can plainly see footage of M1147 AMP and compare it against any footage of the Carl Gustav 84mm and see that the firepower is incomparable.
I don't need experience to see the difference between the two weapons. Speed, penetration, range, accuracy. Completely incomparable.
Tanks were shooting 3000m in the 80s and have probably gotten better. Carl Gustav needs laser guidance for 2000m and even then is still outranged by decades old tanks.
But feel free to tell me which recoilless rifle that is comparable.
