Using Iraq as a metric is a terrible idea given how pitiful the Iraqi military was when it came to general competence.
This is just something I had to shake my head at.
Iraq was far from incompetent. They were actually one of the most competent militaries in the region. With little to give it away beforehand they conducted a 5 division invasion at 2AM which caught Kuwaiti forces completely off guard. They were able to keep the Kuwaiti Air Force so tied up that they could target very few ground forces. They lost 20% of their air assets, then had to run and land in Saudi Arabia because their ground bases by then were being overrun.
By nightfall of the first day, they had secured all of their military objectives. They had eliminated the Kuwaiti military (air, land, and sea) as an effective force and only a few scattered units that were able to turn tail and run made it to the safety of Saudi Arabia.
And that is "pitiful"? Holy crap, that is the exact opposite of what that means.
The reason they were destroyed piecemeal by the coalition forces are many. For one, there was a large technology gap, that no amount of numbers of equipment could offset. Also the bulk of their military were conscripts, with little training who had been drafted between the invasion itself and the start of ground operations by coalition forces in 1991.
Then you have the effect of the US deception operations. One of the most forgotten aspects of the war is the large amounts of time dedicated towards Marines in the theater. Saddam and his forces believed that the main thrust would come form the 2nd Marine Division, sitting off-shore in their amphibious ships. A lot of time was spent by those forces doing all the steps of conducting an amphibious assault, only to turn around at the last minute and return to their ships.
Back in 1992 I was shown photos of the giant sand table set up in a gym in Kuwait City. On it you had about 20 miles of coastline replicated over an area the size of a basketball court. And they had been watching, all of the defenses (being regularly bombarded by the BBs) were pointed out to sea, and they knew what ships were where, with what Marine units. They really were preparing to fight something like the Battle of Iwo Jima or Tarawa all over again.
But it was all a ruse. He and his Generals assumed no other invasion was possible (other than a single column from the South) because such attacks are almost impossible. Except he did not count on a relatively new US development that was already in place. GPS. The coalition forces did not have to follow the maps, did not have to stay on the roads. They simply went cross-country, something no other military in the region had ever been able to do before.
And caught them from the South and West, while they were looking to the East. And yes, the Marines did indeed make their landing. Via helicopter, they took and held Kuwait City Airport. The landing craft stayed inside the ships.
The US also spent a huge amount of time destroying any communications they could find. By the time the ground war started, almost no Iraqi military units were transmitting anything. As soon as they would try to fire up even a Regimental sized command post, coalition fighters were coming in to take it out. Almost their entire C&C system was dark because command posts knew if they started transmitting instructions they would have missiles coming shortly afterwards.
In fact, they learned from this and actually did much better in 2003. With the advent of the Internet, a lot of their communications traffic in 2003 was actually via the Internet and not broadcast. Even the US found it had a hard time circumventing that.
This is the fallacy I keep seeing over and over again. People who seriously under-estimate the capabilities of their enemies. If anything, their biggest problem was the reliance upon the adapted "Warsaw Pact" doctrines that had been taught to them by their Soviet military advisors. That is a doctrine that has failed over and over again since WWII. And it only worked then because it was employed by a massive country with bodies to spare to throw at the enemy. Every time it was tried against more modern military forces it has failed.
But yea, continue to fool yourself that they were incompetent. I am sure you also believe all German soldiers were fat and wore lederhosen, and the Japanese soldiers all wore glasses and had buck teeth.
