So doing some calculations, a "scale" A5 Juggernaught would be about 4 feet long by 3 feet high. Seriously... And that's the small one.

Actually it seems like Juggernaughts are one of those SW vehicles that could come in a wide variety of sizes, and thus there's A5, A6 listings... If this toy comes in small, and I'm sure it will at this point, I suppose I could BS it as a smaller more mobile version... An A2 maybe.

Seriously though, the A5 is the "small" Juggernaught, smaller than the A6 which is what was in ROTS on the Kashyyyk beaches, and that thing by comparison is comically massive. The A5's not far off from an AT-AT's length and about 5 to 7 meters more squat.
