Re: DCV of Stationary Object
The formula for the area of an equilateral, equiangular (aka regular) hexagon, where Z is the distance between opposite sides, is:
area = Z^2 * sqrt(0.75)
where sqrt() is the square-root function.
For a 2-meter hexagon, the area is ~ 3.464 square meters.
However, this is unimportant. The important matter is the size of the target object, relative to a human being. Via "Shrinking" a target half human height has a +2 DCV; via the "Combat Modifiers Table" such an object imposes a -2 to OCV. That, however, is at 1/2 the height; your target is ~61% the height so I'd be inclined to give it +1 DCV (or impose -1 to the attackers OCV).
Since an umoving target has a standard DCV of 3, your E ride -- sorry, E target -- has a DCV of 4 (or effectively 4 if you modify the attacker's OCV).
