This is a posable action figure from the Revoltech series.
No, it's not a military jet fighter. It's the newest Mecha from Muv Luv, the F-18E Super Hornet. Like all revoltech figures the Super Hornet has some amazing amount of articulation and an incredible level of detail.
Please note that the photos shown are of a prototype; the production version may vary. Also, figures such as this are mass produced and as a result some inconsistencies in finish and painting may occur; these are not considered manufacturer's defects. If you absolutely must have perfection, prepare to do some touch-up work on your own.
