This tag encompasses the most recognizable [[Zaku]] variants from the [[Gundam]] franchise. The F and J-type are near indistinguishable except for the lack of verniers on the J-type, which is designed for ground combat. However, the original design of the F-type is identical to that of the J-type thus making it difficult to distinguish the two. 

For Danbooru purposes, these different models should be treated as one and the same.
