There isnt a set of rules that say a certain A/C can take off or land on a rough field, N1K2's had notoriously bad landing gear and were used from some dirt strip on a rock in the middle of the ocean, and for the thing where you said aircraft that were suited to land on dirt, if it has wheels it is suited to land anywhere, some A/C were just better prepaired, like many before me have said to you, I think you need to do more research and then come back with a better argument then just spitfires couldnt land on dirt
Did you even read any of my posts? Read the one above you for starters.
A dirt strip is not a rough field. A dirt strip can have its surface compacted with bulldozers. It creates a very flat hard surface. A very flat hard surface is easy to land on.
No any aircraft that has wheels is not suited to land anywhere. There are reasons that certain aircraft were stationed in some locations while others were not. That reason is suitability.
I'd like you to go and find where I said Spitfires could not land on dirt. You will be looking for a long time.
Once again, could you land a spitfire on a rudimentary strip, with rocks and grass and holes all over it. Sure you could. If you didn't mind constantly servicing it, or didn't mind replacing a pilot when he got injured or killed, or the entire aircraft whenever it hit one of those things on the runway and went out of control.
