When you see that first video it should be a lesson to all civilians not to ever question the actions of soldiers under fire. Regardless of politics the soldiers main objective is to get home in one piece. None of them give a fuck about the politics only about survival, however, they will do the job they are asked to do no questions asked and they will do it with 110% effort because if they don't they or their buddies will die.
Always support your soldiers no matter what even if you don't beleive in the reason/cause that they are there for.
...If you don't go off at least once a season you are not trying hard enough...
