Some of the other reviews state this was the fourth and final Billy Jack movie, when it was in fact the third movie featuring the Billy Jack character. It follows on from The Trial of Billy Jack (1974) and is followed by The Return of Billy Jack (1986).
There is also speculation that the film has been heavily cut, from the original runtime of 1 55 to 114 minutes for the video release. Seems to me there is a good chance 155 isn't the runtime in minutes, but is the runtime in hours and minutes = 1h55m. The video release was 1h54m, as is the version available on streaming services. The NTSC DVD release was 1h50m, so that version does appear to have had some edits.
