These days, two exhibitions of military technologies are held simultaneously. AUSA 2021 has opened in the United States, where defense industry enterprises present their latest developments to the military. In Russia, the Interpoltech exhibition brought together professionals in the field of digital security.
It is not quite right to directly compare these two events — the Russian "Army" corresponds more to the American AUSA. However, after watching videos from the official YouTube channels of the US Army and the Russian government channel Zvezda, you can evaluate the expositions, look for differences, and also compare the styles of presenting information.
