This poster's post count and country of origin make me think he is familiar with Superman from the recent Man of Steel movie, like millions around the world, and not the comics, which has regular readership, easy to forget, that is only in the thousands, an order of magnitude lower.
Or, if he is familiar with the comics, has reading largely confined to Grant Morrison's Action Comics run, which should just by now have become available as a purchase-able foreign trade.
Recall, in Man of Steel, for instance, that Faora, mighty as she is, is felled by a single cruise missile, not because the blast itself is powerful enough to knock her out, but because, exposed to so much stimulus immediately after gaining her superpower, she suffers sensory overload once her armor is stripped.
In the Action Comics run, recall Clark is not only SEVERELY injured by a tank's mortar blast, and actually saved by the civilians he is trying to protect, he is initially captured when a derailed train knocks him out.
There is certainly room for thinking the number of soldiers listed in this thread could take Superman down if either of the most popular WORLD known, as opposed to specifically American known, incarnations of Superman are being used.
