"Why all the NATO countries aren't supplying more heavy hardware and long range missiles is beyond me"

Actually for very practical reasons. Apart from the fear of escalation with RuZZia but this seems to be diminishing, the Ukranians dont have much experience or training with a lot of NATO heavy weapon systems. For eg I assume it would take months to train someone up on a Patriot Missile System. Even smaller weapon systems like the Switchblade, they had to send Ukranians to the USA to train up on it.

I mean there is basic training to become competent then there is time to become proficient and then expert. Long process. KISS principle. Simple and small weapons more accessible.
