cross shaped object heading south Northwest. while being chased by three solid black helicopters

i walked outside at 12:01 AM and i saw two cross objects coming from the southeast heading Northwest. the object speed was about the same as the helicopters.the lights no the objects where lime green red and violet. as i observe the object it started to be obscured by trees the helicopters were still chasing the objects when the moved out of sight. the next day multiple millitary helicopters were flying around the area and hovering.
