Except when a congressman from Ohio decides that they need more tanks so that he can keep his voters employed [1], despite the army saying they have plenty and don't know what to do with them. They have literally thousands of tanks sitting in storage in the desert, and they're rolling tanks straight off the production line into storage.
The army did not convince Congress that it did not need more tanks in 2011, so in 2013, Congress funded an additional tanks to be built at a cost of ~$270M.
Usually, the military provides requirement and the civilian administration provides the funds. How can the Congress order the Army to make more tanks when they don't need it? I am not an American, so probably I am missing the entire context here.
This at least sometimes happens in Europe too... defense procurement is big business and very political, and sometimes European militaries end up in programs (esp. multinational ones) they aren't that enthusiastic about. Another example is conscription. The Swedish military wanted conscription to be abolished for years before it actually happened, but until the civilian government decided to do so, in the meantime the military had to keep taking in and training conscripts they didn't actually want.
They're literally making tanks and driving them straight into storage because the army doesn't have anything to use them for or anybody to drive them.
1. demand is generated by the military
2. bid out contract
3. selected a bidder (bidders are defense contractors)
4. deliver contracted goods and also maintain inventory parts and tooling for sometimes up to 25 years
5. local economy becomes dependent on this manufacturing income, bidder lobbies their local congressperson directly or indirectly
6. congressperson does these wacky ass requisition appropriations
7. the factory keeps production at the same level and with same employment
8. military gets delivery for goods they never wanted so they go into storage, because what else are you supposed to do with these things? You can't resell them because it contains military secrets, you can't scrap them from both an optics level and the general military logic that having a spare is generally fine.
This happens even moreso when it is navy vessels that are much larger cost investments (submarines and destroyers) as just making one will take years potentially and there are legitimate concerns for stopping the means of production but it really just turns into a jobs/national pride story.
As an example, the HMS Queen Elizabeth, the Royal Navy's new carrier, was ordered in 20089 and laid down in 2014, it was commissioned only last year, and is still undergoing sea trials and isn't operational (they also have no planes to fly off it). It's planned to be in service in 2020, 6 years after being laid down and 12 years after it was ordered.
I'm also not sure in the comparison between foreign governments and US defense contractors but US defense contractors generally only sell to the military markets (domestic or international) so it's not like their facilities are designed to be able to build ordinary commercial goods side by side with the military spec hardware.
You see, the army is controlled by the president. The president may be from a different political party or even be following his own personal agenda. The army must strictly obey orders according to the chain of command, and the president is at the top.
If the president dislikes tanks, he can order the army to place tanks into storage and claim that the tanks are not wanted. Congress is left wondering if the people in the army are stating their true expert opinions or just following orders.
Here is a real case that leaked out:

So yes, the military being ordered to lie to congress is a real thing.
The A10 is an example of Congress imposing civilian priorities on the military. Despite its declining military utility, it's a popular plane, so Congress won't let the military sunset it. It has nothing to do with the president ordering the military to lie to Congress.
You're not even legally correct... while the president is the commander in chief, Congress has oversight of military spending under Article I, Section 8. An order to lie to Congress about spending would be an illegal order, and military personnel are not compelled to follow illegal orders.
The F22 looks to be a similar case. Here we don't have a crude effort getting leaked, but that doesn't mean the situation was any more legitimate. It very much seems that Obama was pushing to kill the F22 and the military marched to his orders.
But you're right and I was wrong. The problem isn't only that politicians / civilians have usurped "supporting the troops" as a shield (as I said), but really any decisions (whether it be made by the military or civilians) cannot be criticized / questioned without a high risk of being labeled unpatriotic.
