I will explain in very very simple terms Sweeney.
Tex Banwell left the REGULAR army after the war and took a job with the Post Office.
And he joined the TERRITORIAL Army. This was a continuation of his service. He kept the same service number, but no more full time service.
His first Territorial unit was 11th Battalion Parachute Regt., and then 10th Battalion who he was with until about 1971.
Yes he was what you call a weekend wannabe soldier, just like Epona over there in the Guard.
Territorials were only concerned with conventional warfare training.
No connection at all with Northern Ireland.
You made all that up.
Why?
