Taiwan's air, sea and land forces launched a military exercise aimed at repelling a simulated invader near Taichung in central Taiwan on Thursday.
Footage shows naval vessels, helicopters and Ching-kuo fighter jets partaking in the drills near a coastal strip.
As many as 8,000 soldiers took part in the live-fire drill.
The drill was modelled on a potential invasion of the island by China and comes at a time where tensions between Beijing and Taiwan have flared up anew.
Beijing sees Taiwan as part of its territory.
