This kit is a combination of the Bronco gun kit and the Dragon 6275 crew kit. The gun can only be presented in the firing position as the travel bogies are not present. The crew can be depicted in either anti-tank mode or anti-aircraft mode. However, the crew instructions included with the Bronco instructions only show them in the anti-tank mode. You can get Dragon 6275 instructions and build the crew in different poses, and even in the anti-aircraft mode, which is what I did.
The basic point to remember when building this kit is that there are numerous small plastic and PE parts. Care should be exercised during the build, and you may even want to delay attaching certain parts until almost the end of the build.
