UFO Sighting in Battle Ground, Washington on March 21st 2016 – Dark UFO being escorted by Chinook Helicopter

I was in the back yard and heard this incoming Chinook Helicopter flying near, close to the ground, very loud, and as it passed into view, just ahead of it was this dark moving craft. Observing both was very short, but I could make out a cigar shape as best as I can describe. It could have diamond shape, or could be a disc on edge, but it was very much something that was making now sound at all and seeing the helicopter so close to it, could see it was being escorted. I have prior reports from the area, and also have not mentioned other strange sightings here, they are very frequent and Battle Ground Wa., is an area UFO watchers should be looking more into these days.
