Deaths in Army: Safety or Physical Fitness?

There is another death that take places in SAF today. This is the 3rd cases of the year.
I have wondered if safety measures have been taken to prevent such things from happening or is it that the physical fitness of Singaporean is dropping.

There has been many deaths reported since last year. If there are more such cases again, will parents ever entrust the safety of their children to the SAF? Will the soldiers be worried or tramatize with serving NS?

Anyway, I think I have no position to judge the above as I have never attended any BMT or Army training. Maybe my friends out there will like to comment about it?
