Claire stands about 7 3/4" tall. That's actually a pretty unusual size for an action figure and I haven't found many other lines that she fits in well with. For quite some time I displayed her and the Regina version of Jill Valentine with my G.I. Joe: Sigma 6 figures. They fit in well there both scale-wise and stylistically.
I get the idea that these were intended to be more like statues that gave you some variety in posing rather than full fledged action figures, due to their somewhat posed nature. Claire features boot swivels, a swivel waist, swivel shoulders, swivel elbows, swivel wrists, and a ball jointed head. She won't stand on her own, so the included stand is necessary. Her boot swivels are really only useful to get her feet lined up evenly--they don't add much to the different poses. The upper body articulation is decent, though, and allows her to hold both her revolver and her machine pistol in a few different poses.
fanning the revolver. The second weapon is not actually from Resident Evil 2, nor Resident Evil 3, but from Resident Evil: Code Veronica: it's one of the M-100 pistols Claire uses in the game. Claire looks pretty awesome with it, even if she never used that gun while in this uniform.
