Covenant portable shield
From Halopedia, the Halo wiki
The Covenant portable shield, formally known as the Pavise of the Worthy and otherwise termed as the Covenant emplaced shield, or the stationary shield generator, is a type of energy shielding device used by Covenant and its splinter factions for the protection of ground troops during military operations.
Portable shields, which come in a number of models, utilize a dissipative shield generator powered by compact power storage cells to project an ovoid-shaped protective energy shield. Using gravitic anchors, the device can be robustly positioned in a desired position. Essentially a larger version of the point defense gauntlet used by Kig-Yar, the shield is used as protection by Covenant soldiers in both offensive operations and in the defense of strategic locations. When shot at, the shield transitions from blue to red in color before finally dissipating and eventually restoring. The shields are effective at deflecting small-arms projectiles, but struggle against explosives or plasma fire.
After the conclusion of the Human-Covenant War, Jul 'Mdama's recently formed Covenant splinter faction frequently utilized portable shields in battle. Used extensively throughout the Battle of Requiem, the Requiem Campaign, and the Blooding Years, the shield provided essential cover for the Covenant's soldiers.
