That, and, what if the weapons are defective?
That said, the support Ukraine IS getting is rather interesting:
Speaking of brains I noticed on videos from war zone that Ukraine has now high technology weapon. Small drones that correct fire and make work of artillery more precise I saw pretty much similar videos on youtube from war in Iraq and Afganistan. Mostly Apache helicopters shooting rockets from 8 kms distance. In Ukraine no helicopters because Russian anti-aircraft everywhere, but there is very small drones, quadrocopters, lot of them with high resolution cameras on board transmitting the picture to Ukraine artillery.
6 month ago no one here knew what is quadrocopters, there was no communicating system for correcting fires. No night vision devices and similar high tech toys. Now Ukraine has more and more of that stuff. Obviously our army being supplied with this by unofficial channels.
