I served in the artillery. I drove . I had to wait for the enemy artillery to zero in, then use the trajectory of the shells to determine their position and transmit it to my own artillery to engage them before they fired from all guns. M777 does not have to zero in, because the first shot is on target.
That's a 1960s system, technology has changed in the past 60 years.
I know. Modern artillery does not have to zero in. Therefore mortar locating radar is obsolete. Shot, hit and hide.
So that's roughly the amount of arms that Ukraine needs to be supplied every 2½ months in order to equip its soldiers? I think that's doable.
Tanks and helicopters need people to operate them. Are you going to be sending those over as well?
According to this, a single M1A1 takes 5 months to manufacture with a throughput of 8 per month. You can hire a few hundred skilled technicians to get it up to 34 per month. This is the only tank manufacturer in the US.
most of those 1 billion have militaries on the scale of Croatia which failed to detect a 1960's uncontrolled drone, Romania which crashed a Mig-21 then crashed a helicopter looking for the crashed Mig-21, etc. On top of that, most just import US weapons so its actually 300 million vs. 140 million. this is a lesson that Chinese learned long ago: having people is great but without organization its just a loose heap of sand.
