I seen that happen with a lot of companies in the defense industry here in the U.S. as well. When the gravy train of the wars in Iraq and Afghanistan wound down, companies that did the same thing you described went through the same challenges. Many are actually closing their doors or are selling out to larger companies.
Pickle ball seems to be something that is catching on. At least over here it is. Who knows, it could be your second career :-)
So much money was made by so few during those times. If I remember correctly, Cheney had his fingers in many of those pies.
I have heard it is huge in the US at the moment. Here, it is "Padel" that is popular, which is a mix of squash and tennis.
Actually quite a few companies popped up out of nowhere during that time. Lots of small businesses to do business with the DoD as they get preference on a lot of contracts.
Yeah, there were some weird shit going on with Cheney and some of his old companies at the beginning of the wars. That is actually what led to some of the wild west to all of the small companies popping up. You get a chance, watch the movie "War Dogs". Although it is sort of a comedy, it is based on a true story. It will explain some of what I am talking about. It is these smaller companies that are now shutting their doors.
Pickle ball does seem to be catching on. I guess there is actually a professional league now with investors and everything. So they have ruined it already.
