Stealth Pelicans in Warzone?

So I’ve been wondering about this for a few months now, as I’m sure others have too. What is the story behind those completely silent stealth Pelicans in Warzone? Is it just a proof of concept or something being tested in WarZone, or is this an actual canon thing that the UNSC has at its disposal? If this is an actual thing, why isn’t it’s use more widespread? I mean, it’s only seen on about 2/3 of Spartan deployments in WarZone. Does the UNSC not have the resources to produce more? Please, 343i, don’t leave us here grasping at straws. Maybe have Grim do a Canon Fodder about these Pelicans, because it’s on our minds and we all want to know.

Ha! This made me chuckle. Almost as funny as the YouTube video of making your own music on the opening cutscene.

Don’t forget the silent stealth drop pods! Those things are awesome in Warzone Assault!
