I want detail of the major advances in weapons primarily.  For
example, Germany -- A7V tank in 1917 - first german tank, (important
characteristics), etc.

Tanks, use of poisonous gas, trench warfare?

And how 'bout that Fokker, developer of the synchronized machinegun
firing through gaps in a spinning propellor.

Big Bertha ... Long range artillery.
