COLO. SPRINGS- A spectacular migration of Army attack helicopters traversed the city sky yesterday, flying south to Ft Carson where they will catch trains to faraway winter fear-breeding grounds in the news.

It took only one Black Hawk Down to terminate US ground operations in Somalia. If you’re hoping such a milestone could be a benchmark for Iraq or Afghanistan, unfortunately “hawk” also denotes the plurality. How many Black Hawk have to go down before Americans cry uncle? This week we are nearer to finding out.

I know I’m mixing Apaches with Chinooks, but I’m grouping all multi-million-dollar vertical-flight aircraft together obviously to note that the US lost three over the weekend in Afghanistan, with a commensurate record setting loss of US soldiers. Which will prove the more alarming?

Earlier in the week, Brazilian paramilitary forces lost a helicopter in a gunfight over a Rio slum, where a war is suspected to have been declared on the poor in preparations for the 2016 Olympics. The significance of sophisticated weaponry downed by common insurgency tactics is not going uncelebrated.

Isn’t it interesting how the official reaction, whether you’re a spokesman for the Brazilian military or Israel’s is to deny any possibility that the aircraft might have been struck by enemy fire? Uniformly that it the denial, which almost always proves untrue. As if even the cause of the crash matters. What’s probably critical to military strategists is that opponents not receive accurate feedback about the effectiveness of whatever tactics they used.

Meaning armchair strategists have no reliable information to go on, other than to keep a tally.
