This is a good use of all your ARAH and VvV molds if you don't like mixing them with 25th and beyond. They make great background filler for a display such as this.
I had this set up in my old apartment but this is the new one and all the COBRA army are now ARAH molds. It's based, if it isn't totally obvious, on the Emperor's arrival in "Return of the Jedi."
And no, all those COBRAs didn't fit on the Rattler, just COBRA Commander and Quicksilver (CC's personal pilot, the silver Strato-Viper, a specific character in my Joe-Verse). The rest were waiting for him.
