this was the most challenging kit in the zvezda 1/100 kits I have yet built. The reason are the rockets. The vehicle itself is very easy only 5 parts. THE FRACKING ROCKETS ON THE OTHER HAND IS 4 per rocket and they are tiny. 1st you get 2 grate pieces make sure the tabs that go into the mount are correct there will be 2 on one side of the rocket launcher. The grates that make the launcher attache to the rocket 1 hole on each side of the rocket. After that you take your rocket mount and attach it to the vehicles sides 3 on each side. Then you mount your rocket launchers to the mounts on the vehicle. This would not have been a hassle in a larger scale but it is what it is. It cones out quite nice but it will be a frustrating journey for us with big fingers.
