The best weapon was the German mg42. It was so good that it is still in service in parts of the world today. It has an immense rate of fire.
During World War II, the 'best' weapon that was designed, constructed, and utilized, when measured in terms of overall power, was the atomic bomb. Through the effective (if also regrettable) use of this weapon, the world-wide conflict was finally brought to a conclusive end in August of 1945.
How can a weapon NOT BE a weapon? Chemical gas attacks, various "automatic" weapons, machine /gatlin guns etc. The biggest weapon. not a weapon in the sense of a single person activating it was the introduction, by the British, of the tank.
British 303
the best weapon ever used in ww1 is the machine gun because it stabelized the front and cuased massive losses on both side
The most deadliest weapon in the world is a Nuclear bomb/Nuclear missle. If it in guns you mean well i say best guns are the MG42, AK47 and the Barrett M82 Sniper rifle. -------- I suppose that now the most dangerous weapon is the hydrogen bomb.
The weapon spread fear into the hearts of the British and French troops at the start of their use .
batons
The British tank was superior and in much greater numbers than the Germans. They helped to terrorize the Germans in the lattter stages of the war. The Germans, totally underestimated the potency of this new weapon.
