I spent 5 years in the Royal Logistics Corps whilst finishing my A Levels / at Uni and had an almost identical experience to Santacruzi (you weren’t in 158 RLC by any chance?) -it definitely beat working at Tescos! I used to attend about two weekends a month + 1x drill nights per week (plus ski trips, WWII battlefield trips…) and as I was a student quite often went in during the week to act as the permanent staffs’ lackey. I didn’t get mobilized but was put onto ‘notice to move’ a couple of times – this was the late 90s/ early 2000s and things have changed now and the majority of my mates still in have all done active service.
If you feel you cannot commit to the ‘normal’ TA (I’ve forgotten the proper term…) you can become a specialist where you only spend a 20ish days per year training and you still receive the full bounty (bonus) .
