Such an unfair blow to family and most especially the blokes parents.. every time a travesty of the most monumental proportion when the child dies before the parent does.
Onto logic...the individuals that died exercised their socially engineered free will to place themselves in the situation they found themselves in, it was their choice, I expect rational under the shallow societal depth regulated today, would they have accepted the paycheck if they knew absolutely of their fate....one must consider no in the near absolute majority...so they chose to roll the dice with their lives and the resultant effect upon their family's if the unbelievable happened.
Personally I believe that all front line armed forces personnel under the age of 33 should be outlawed....the armed forces (government) preys on the young's lack of a fuller developed wisdom through targeting directly the psychological understanding that only maturity or past directly suffered threats like sickness/trauma related at one's life can replace any young individuals personal belief in their relative near absolute immortality.
It's a sentient being thing....a rule...and a travesty when government/s cannot/will not recognize the simple most base reality's of what/why being being human means.
