I remember reading that most Covenant ships implemented energy shields. However, in Doctor Halsey's notes, it was stated that a UNSC ship couldn't generate enough power for a energy sheild arouns a compartment or an entire ship. However, she was able to create a shield generater in Mark V MJOLNIR armor and in Halo Reach's MARK IV MJOLNIR Armor that is smaller than a shoebox, then couldn't she find a way using a reactor to generate a shield around a ship? Also if they were able to copy covenant technology as far as active camoflague, then why can't they copy covenant weaponry? Let me know what you think.
