What happened to Lennox Greene's military career and why?

Lennox Greene, once a promising Royal Marine, destroyed his military career due to his involvement with cannabis cultivation. As revealed in the clip, authorities discovered exactly 57 cannabis plants connected to Greene, which led to serious legal consequences. This criminal activity resulted in his dishonorable discharge from the Royal Marines and placed him at the center of what is described as a 'love triangle' and 'chaotic drama.' Greene's fall from a respected military position to facing legal troubles demonstrates how quickly poor decisions can derail a promising future.
