I have a great idea for Halo 4. I dont know if the jackels are in halo 4 or another enemy but wouldnt it be cool if you are able to pick up their potable shields as they do in the books and use it as a riot sheild like in call of duty (still being able to use pistols like the plasma pistol). I think this would be a great new edition to Halo 4
Maybe for one mission or part of a mission, maybe in custom games too (just for the lolz). But if they were in matchmaking it would become the new armourlock 
It’s been thought of many times before. The primary issue is being able to see anything at all.

That could be a disadvantage of using it. You gain protection, but lose some vision.
