What do you think about the article, "US Air Force Manipulated A-10 Casualty Data?"

LTC Labrador - Agreed, enough said.

Russia & China are 2 BIG reasons to keep the Hawg. Those two countries rely on tanks & movement of ground troops that would be ideal targets for a GAU strike.

I couldn't agree more SSgt (Join to see) .

That was my point. The US is still set up for mass-attrition warfare, Russia has moved on from its Soviet past to develop a doctrine more similar to China's unrestricted warfare that uses social media, economics, cyber attacks, deception and proxies.

I agree completely that the US needs to be ready for varying threats, however I find it unlikely that any adversary the US is likely to face would be foolish enough to throw its armored units out against us. They already know what the results would be. In my opinion that would most likely deploy dispersed infantry armed with advanced man portable anti-air and armor weaponry.
Egypt did this to absolutely devastating effect against the Israelis in 1973. This however, does not lessen the importance of the A10 which is what this is all about. On the contrary this will mean that American forces will be further outnumbered and engaged at closer ranges than before where the close in (within visual eyesight), low altitude abilities of the A10 will be absolutely indispensable.
On your other point, PRC is indeed a threat but less than many would believe. Their primary concern at this time has been to create denial of access capabilities to prevent free exercise of our Naval superiority in the South China Sea. This has taken the form mostly of naval aircraft and missile developments. While they may move into long-range power projection, they are yet to cross that bridge. The same is true of Russia, they are more concerned with their "near-abroad" than directly challenging the US globally. Where we come into conflict here is that the US cannot allow any single nation or group of nations in a single region to gain enough power to challenge our hegemony there. Russia and China both have designs tonact as regional hegemons, a concept that is directly counter to our national security strategy.
This does not mean however we will engage them directly. This is extremely unlikely, even taking into account the hypothetical I posed above. All three powers. The US, the PRV and Russia are all nuclear powers and no nuclear power has yet fought another nuclear power in open warfare; the risks are simply to high. Far more likely is containment, such as our recent increase in relations with India to subvert Chinese influence and proxy conflcit such as Russia has employed in Ukraine to excellent effect.
