Some comments question the accuracy.

Australia is still a nation that invents and sends its inventions around the world. Just last week there were two announcements for export of a modified Bushmaster which gives its troop carrying capability away in exchange for a mobile missile launcher. It is believed that Norway will be the first buyer and this has similar capabilities to the US-developed HIMARS system - basically missile defence, though the modified Bushmaster vehicles retain the ability to move around whilst being immune to roadside bombs. The other development is a death ray, a 150kW laser that can shoot down dozens of drones per minute to defend an area against the types of drone attacks that Russia is inflicting on Ukraine at the moment. Ukraine will purchase at least some of these lasers.

Sadly, all the large conglomerates are now gone. AWA, Thorn-EMI, Philips and Email being the main ones. All had their divisions either split up, dissolved or a bit of both and all are shadows of their former selves.

As for the facts in the video, I saw this about a week ago - it is mostly correct but there are a few small inaccuracies. These sorts of videos rarely get everything correct.
