The above complaint, and editing of some article sources as unreliable, seem to be baseless nationalism. Most military performance statistics are either classified or cannot be independently verified. And most countries have exaggerated weapon statistics at one point or another (for example the American TOW missile system greatly inflated armor penetration values). As the complainer hasn't gone through every single military article (or even the ones linked to this one) and labeled any claimed statistics as unreliable unless they were verified by independent tests, I'd have to assume his complaint and edit is based just on personal bias. Unless the complainer can find an independent source that tested the weapons, the claimed official specifications ARE the most reliable source.
