Rambo's skills. A question?

Would a special forces operative like Rambo really know how to drive tanks and fly helicopters?

In the early Cameron-script, that James Cameron wrote before Stallone did all the re-writes, Rambo has a line where he specifically mentions being cross-trained as a heli pilot. Now, I don't know how the training programs in the US armed forces work, but looking at it from a purely tactical point of view, would it not be advantageous for a spec ops team to have their own pilot in the group, just in case the group needs to evacuate and have a bird at their disposal, but for some reason the dedicated pilot is dead/has disappeared for whatever reason. In the case of this movie, it certainly proved to be a life saver skill for both Rambo and the POWs. Without Rambo's piloting skills and the Huey's firepower, defeating the camp's soldiers and extracting the POWs would've likely been too much even for Rambo.

It's not entirely out of the realm of possibility. I enlisted in the Navy as a Mineman (MN), which is mine countermeasures, or essentially explosives disposal. I was cross-trained in aviation electronics as well. This was due to necessity, and my ASVAB score. I'd imagine that the Army would cross-train academic or physical Spec-Op standouts in other areas besides combat effectiveness/readiness if the need arises.

The Vietnam War was basically the first deployment of the Green Berets. Their training was very special. They operated in very small groups, completely cut off from support, and in the beginning of the war mostly trained south vietnamese troops and assisted them.
Later in the war they had...varied missions.

But their training embraced the philosophy that every member of a Special Forces team needed to know how to do each others job. Now, they likely would have had a helicopter pilot who was really good at flying on the team, but a few others would have to at least know how to fly adequately. Same for medics. Kinda like SEALs today who have medics who carry some extra gear, but everyone needed to know how to be their own medic. They'd have a good radioman, but everyone would need to know how to use the comms gear proficiently, same for demo, sniper, every job.

They were also trained in how to use an operate any firearm or artillery piece they might find in the field...which meant learning all U.S. hardware, Russian hardware, and French hardware, plus an assortment of German and British gear too. If they came upon a Russian tank, someone on the team needed to know how to drive it in case they needed to use it.

And yes, the training took a long damn time and meant a lot of traveling and weird deployments for Green Berets, especially when it was a new concept.

Of course, the training has evolved since then, but that's what it was like back in Rambo's day.

Originally I wasn't sure if a special force operative like a Rambo would know how to fly a helicopter, however after playing the the Rambo video game on the Commodore 64 computer, its fully established that Rambo did indeed have the skills needed in flying a helicopter

When I was in the Marines in the 90s and early 2000s, we did a lot of cross training. For example, setting up and firing 81mm mortars is a specific skill that takes time and practice to master. However, I was shown the basics and I physically worked through the process with guidance from the "tube strokers."

And while I could certainly setup and operate, I wouldn't necessarily be able to put rounds on target. But I can put rounds toward the target, so there's at least that.

I also spent a lot of time showing infantry how to do what I did, in case I went down in a firefight, they could at least know the basics.
