Hundreds of exhibitors and countries showcased their military might by displaying hi-tech armoured vehicles, missiles, rifles, drones, submarines and more.

There were regular messages aired through speakers to keep the mask on. Volunteers were on the ground with placards urging everyone to maintain safe distancing and they would make a dash at any group not following the precautionary norms.
