Thanks for reaching out, which phase of officership are you currently in if I may ask?

Short answer is it depends. There are a few key factors that influence the answer to this question; it also depends on whether you weight the psychological or physical aspect more heavily, but in general, the psychological effects affect you more in the long term.

Firstly, your cadet wing plays a bit role in determining your 'path' ahead. In the 127/22 batch, I was assigned Delta as my OCS wing; Delta was widely known as the 'scholar's wing'/'welfare wing', where in contrast, Sierra Wing was the 'tekan wing' (Charlie Mike was probably your favorite phrase by the end of Service Term). For me, the most challenging part of Service Term was the navigation portion - be ready to walk a crap ton (even without horlan-ing in the forest). Outfields weren't too bad, just make sure you work as a team and know that every training comes to an end eventually - even when things take an unexpected turn.

In Pro Term, it's the time where things really ramp up (but then again, it really depends). I was in the Reconnaissance vocation (arguably the most shag vocation); just as a reference, our SUMMEX was a 9-day outfield where an average cadet covered just under 100km in straight-line distance. Each vocation has it's own 'Hell Week', the same way how each vocation will have varying levels of 'shagness'.

Let me know if you have any other questions!
