Halo's got shittier weapons, shittier armor, way less soldiers, no unmanned robots, no shawken device, no sun crusher, the list goes on and on. Every precursor tech is made through neural physics which is indestructible but very destructible to the halos. Star Wars can jack a halo (but they wouldn't have to do that anyways cuz Star Wars can make it on their own or maybe even better) and just destroy every precursor tech right there
