Military Sides In National Sports Leagues

Military Sides In National Sports Leagues

In the USA, the armed service academy sides often have sides playing in the College Sports.

I wonder if other country's military sides could play in the National sports leagues of traditional club sides?

Where the top sides of senior players of adult age take part in the national sports leagues. 

Plus the youth sides could take part in youth leagues. 

For instance in terms of national domestic leagues;

Could the regiments, navy, air forces, bases play sides in nation domestic sports leagues against the non-military sides?

Like for instance Scottish regiments entering sides in the Scottish football league pyramid, or the Scottish rugby union pyramid? 

Could we have The Scots Guards, or Royal Scots playing in the SPFL? 

If university sides can why not armed forces sides?

Or at least could armed forces, Navy / Air Force sides take part in the Scottish Cup, or regional Cups like the Aberdeenshire Cup, Glasgow Cup, and North of Scotland Cup?

Could regiments, bases, or combined forces enter sides in the Scottish, Welsh, English, Northern Irish, or the leagues / cups of sports and in the sports that have combined United Kingdom sports leagues or cups? 

Could the Royal Marines enter a side in the English FA Cup?

Could the Welsh Guards enter sides in the Welsh football pyramid or Welsh Cup?

They could even qualify for European, or continental trophies.

Sports leagues where the forces sides could take part could include sports such as football, rugby league, rugby union, cricket, tennis, darts, snooker, bowling, bowls, gridiron, basketball, baseball, ice hockey, poker, computer games, chess, field hockey, netball, athletics, swimming, motor sports, shinty, Gaelic sports, handball, strength sports, polo, water polo, martial arts, equestrian sports, and badminton.

There could even be foreign army sides taking part if they have bases in the country!

This could happen at male and female sport. 

Other countries could do the same like Canada, France. Germany, Spain, Italy, Australia, New Zealand, South Africa, Brazil, Argentina, India, China, Singapore, Poland, Switzerland, the Netherlands, and Belgium.
