Btw I always felt that laser on shield == nuclear explosion idea was rather bad, as it has immense exploitable military potential which somehow wasn't utilized at all in the books. I understand that it was made to explain why they suddenly fight with knives and swords instead of projectiles and lasers, and while the explanation works for projectiles, the laser explanation fails.
