On March 4, Brigadier General Edgard Arevalo, the AFP spokesperson, said around 6,500 US forces and 4,300 Filipino troops are expected to participate in this year's iteration of Balikatan. The number is almost double than last year's Balikatan participants of 3,500 American and 4,000 Filipino troops.

Balikatan, a Tagalog phrase for shoulder-to-shoulder, is the most comprehensive among several annual or regular US-Philippines joint military exercises that aims to develop Philippine combat readiness and US- AFP interoperability.

The Philippines now has 707 confirmed COVID-19 cases, including 45 deaths.
