Benefits (How this will benefit the server and game as a whole): The current riot shield is completely useless against humans and mostly useless against aliens. Giving it to MP will give them a cool toy with no real impact on balance, while improving the rest will result in more varied gameplay.
Details (Description of how you think this would work, the benefits, etc): The ballistic shield would be a heavy, futuristic version of the ones currently used by police and special forces during intense firefights, intended for military use, and thus designed to stop a rifle-caliber bullet at close range.
While the same at CQC as the riot shield (except bash damage would be on par with the marine knife), it would block 100% of ranged attacks unless pierced by AP bullets.
It would come with a back slot "harness" acting essentially as a holster for it. Using the shield without the harness would require two hands. The harness could also have two to four slots for miscellaneous items to act as a small backpack.
Alien spit would gradually wear down the shield. Plasteel or large amounts of metal would restore effectiveness, while chitin plate or resin paste would give it a limited immunity to that effect.
Implementation (Optional, if you have an idea how to implement it): Add a "shield holster" harness that goes into the back slot. Clone the riot shield and improve it's anti-ranged capabilities. Acid interaction and repair/improvement optional.
