well,there are alot of factors at play here, basically, a chinook can be brought down by a few AK bullets in the right place, so an RPG can do massive dammage, as seen by a battle in Iraq, where 2 chinooks were shot down on a snowy peak, both the origanal chopper, and the chopper of the US Army Rangers sent to rescue them, (sounds a little bit like a repeat of Black Hawk Down eh)but whether it was a real attack or not is unknown, here in Australia we had an incident with the news reporting a black hawk with SASR personel (Australian Special Forces) being shot down, when it turned out to be an accident which the taliban claimed responsibility for,so the details are unclear or not, its even weirder that 20 of these men who dies are SEALs, the same men who took down Osama, a twist of fate, or a leak in intellegence?, once again the issues are unknown, now whether you agree with the war or not, you must remember that these re 30, young, well trained men, who gave up their lives for something that they personally believed in, it IS a tragedy to loose such men who had families waiting at home for them, infact its a tradgedy to loose anyone,whether it be 70 innocent dead at the hands of a phsycotic madman in norway, or the deaths in conflict at the hands of an enemy, too fighting strong for what they believe in (im NOT refering to islam here), my condolences go across to everyone across the world who has been affected byt he current events, the wars, and the global disasters, I think a qoute from general patton also applies to the situation, "it is foolish and wrong to mourn the men who died, rather we should thank god that such men lived." good to see everyone taking this topic maturely
