First of all, given the overwhelming number of drones being used by both sides, Australia would have to supply thousands of Slinger systems to make much difference. That's obviously not going to happen. Secondly, the real "game changer" in this equation is the inability of European NATO members to supply sufficient munitions and the desire of the US Repubican Party to hand Ukraine to Putin by blocking all further US aid. We've heard so many "game changer" stories over the last 30 months that more of the same is not merely complacent nonsense but actively mendacious. Oh, and where are those "game-changing" F-16s that were supposed to have been on their way a year ago....?
