Covenant portable shield

Did you mean the Halo 3 Covenant Equipment, the Deployable Cover?

A Stationary Shield Generator is a device used by the Covenant during offensive ground operations. These shields are larger versions of the Point Defense Gauntlet used by Jackals, some Spartans, and some Elites. They are created by three small portable generators that are attached together and, when activated, provide extra protection for the Covenant troops. These are normally placed at strategic locations, like doors or building entrances, when the Covenant are guarding a small, temporary position. This information is derived from first-hand accounts, though it is unknown how the energy fields are generated. They can deflect all projectiles except rockets, explosions, or large amounts of plasma fire. In Halo: Combat Evolved if one of these shields is hit by a vehicle, it will be permanently disabled. In Halo 2, vehicles cannot collapse them on impact. In Halo 3 it reappears or was remade as a piece of Equipment, the Deployable Cover, where it can be deployed by troops.

Trivia

 * It is unknown why you can't be seen by the Covenant behind one of these shields. It was suggested that the Stationary Shield Generators acted as a wall to the AIs.
 * If you fire at a shield with a human weapon, the shots may bounce back and do actual harm to you. This can be graphically demonstrated with a Sniper Rifle, and there have been instances of multiplayer suicides due to that particular scenario occurring.
 * Only Plasma-based weapons are able to temporarily overload the shield's generator.
 * If you have a Shotgun, or other long barreled weapon, and you walk right up against it, the barrel goes through and you can shoot through it at opposing enemies. Similarly, it is possible to snipe enemies while never having to expose yourself and take cover again. In Halo: Combat Evolved, this should be attempted carefully, as the Sniper Rifle must be a certain length out of the shield for it to fire through it. The bullet will otherwise deflect off of the shield and hit the user of the rifle.
 * In Halo 2 on the level Delta Halo, shoot one of the stationary shield generators until it temporarily goes out. Get in a Ghost, and drive it onto the base of the generator. When it comes back up, it will flip the Ghost into the air, this will work on any vehicle, even a Scorpion Tank.
