Generic camo is super easy and no taping is needed. With the wide spread availability of flat greens and browns in sporting goods stores, you can make it look good easily.
The classic German camo takes a little work to look right. You can't go wrong with the US Army's black and white (or yellow) roll pattern. It looks good but takes some effort also.

My uncle was a company clerk for a P-47 squadron in Europe in 44-45. He said a couple of captured V-2's made a stop at his base for a day or two on their way to being shipped to the US. He remembered them being solid green. I don't know how many operational V-2's were painted that way vs camo. If the majority were, that would be the easiest and most accurate paint scheme. I imagine they used the same shade of green as their panzers and planes.

Of course, Bunny's didn't need painting.
