I've tried to Google what this shirt may be called, but all I get are ebay links and links for the Combat Uniform (which is a different beast)
On the BBC/Cinemax show "Chris Ryan's Strike Back" (or just "Strike Back"), the British soldiers are shown wearing this top, and I was wonndering if it's a "TV fabrication" or a real item.

It has no shoulder pockets (or apparently any pockets on the sleeves), and it has a button-down rank tab and pocket flaps. The Union Jack is apparently sewn directly to the sleeve. It does not appear to have a mandarin collar.

Some of the uniform collar points have a button on them, but I haven't been able to make out a corresponding button hole on the other collar point.
So, is it a "real" item?
If so, what is it called?
TIA
