This is a completed and painted, fixed-pose figure.
From the Good Smile Company website:
From "Strike Witches: Operation Victory Arrow" comes a figure of Erica Hartmann based on the illustration by Fumikane Shimada that was included as a bonus with the Blu-ray and DVD of the movie! Her innocent smile and cute appearance has been sculpted and painted by Hajime Kouduki. Enjoy Erica by your side in a rather different look to her normal uniform!
