What autocannon should our future AFVs be armed with?

Stick with 25mm? Go up to 30mm? Try out 35mm or 40mm or some other?

There'll be a need to balance lethality, commonality (usability in other platforms like AA and naval), and practicality (cost).

Alam ko Royal Ordnance has this 20mm auto-cannon na pwedeng isalpak sa mga light vessels. It would be nice if this can be made uniform for the PN and Marines. Maybe for the other services as well. Problem lang ay is the 20mm ammo enough. Kung mas malaking ammo mas malakas siguro problem naman would be the cost and space issue.
