This is entirely my own opinion, but I can't helping considering those Recruits/ Officer Cadets who VR simply because of limited access to the outside world as being misfits for the military. Everyone enrolling into the military knows (or should know) that they can be deployed overseas for months on end, and based on the secracy associated with the mission, outside contact may be limited.
Apart from all this, the very purpose of indoctrination is to break down and rebuild.
When I was a residential university student (in India), all first year students had to go through a three month period of "ragging" by the seniors. Mind you, any form of ragging is by law illegal in India. But we were all in a new city for the first time away from home, so deciding to complain never even crossed our minds. I am not condoning what we went through, because a lot of it would be termed as "torture" and "inhumane" in the western world.
Some of what we went through was - "falling in" from 21:00 to 05:00 hours, repeated slaps during the fall in period, five minute wake up calls through out the night, ironing over 100 cloths a day (belonging to the seniors), not allowed to step outside the hostel (there was only one phone on which calls could only be received and obviously this was reserved for the senior students. Cell phones were too new and none of us could afford them. This was in 98), standing straight and looking directly up at a point on the ceiling for hours, cleaning the toilets and rooms of the senior students, measuring the floor with a coin and if there was a discrepancy there would be that many slaps, etc, etc. Oh yes, the boys had to have their heads shaved during this period. One last detail - guys ragged guys and girls ragged girls.
Again, I would not like anyone to go through this. The worst was the slaps. I'm talking hard back-handed slaps, not a little rap on the cheek. (One of my friends broke his tooth). What I'm trying to get at, is that going through all this turture strengthened as as a class. There were 30 of us and all of us helped each other out. Say if I was tasked with irons the cloths and a class who had missed being given a task, would automatically help me out (on the sly). We were one united body and all of us are still in contact with each other. Looking back now, we should not have put up with all that crap and should've gone to the police and the university.
Coming back to the basic training at CFLRS. I'm certain that if there was a death or some other serious situation in my family and they contacted the school, they will give me the time to make the necessary calls. So, what is the big deal if I dont have access to my cell phone?! This is Canada, one of the richest and most modern country in the world. Its not the CFLRS is located at Timbuktu!
Again, all the above is my own opinion. Others may agree or disagree.
