They refit the PoA really quickly. And, as I stated above, we already have DEW weapons. There would definitely be improvements in 500 years with DEW weaponry. So basically, they could outfit a really small battlefleet with large particle beam cannons and that would help punch through shields. then the MAC would finish it off.
