Here you say that you can read books to fight better in jungles
And here you say that you cannot train to fight better in deserts
Are you trying to engage in a serious discussion, or are you just trying to "win" by very dubious interpretations of semantics? Because really, the latter doesn't work on me and makes me shrug at people's inability to focus on the facts and constant attempts to avoid "defeat" through semantic gymnastics.
And ad-hominem claiming I don't know about desert warfare? Please. Ask me a really tough question, like how many trucks it would take to supply the 3 additional Panzer Divisions Rommel requested but didn't know the logistics requirements to.
Anyway...
You can learn about jungle combat and survival from books written by people who previously experienced it. This is fact. This is why there are no quotes when I say training in this regard.
However, your source claims German "training" in the desert, which I enclose in quotes because the sort of "training" they tried to implement was, in a word, retarded and could not be considered to be real training. Why do you think I used quotes and then further defined what that "training" actually was? Really, you entirely ignored this bit:
The Germans had this notion that they could "train" their men to "get used" to the desert and eventually reduce their water rations, but in reality that just got more of their men killed by heatstroke.
Again, we are talking about an Afrika Korps who thought you can "train" a person to drink less water in the desert. This is not only wrong, this is criminally negligent and stupid which cost men their lives due to heatstroke.
Trying to pretend there is any sort of inconsistent positioning here is simply shying away from the fact that the Afrika Korps in fact had one of the most retarded "training" courses on desert warfare ever, which claims that you can train people to drink less water in the desert. But really, what do you expect from a Nazi Germany that loves emebelleshing pointless titles on units, and yet is so stupid on the scientific front that it rejects the theory of relativity in favor of a theory that claims the sun is a giant ball of ice?
The fact that you keep claiming that a source which advocates "drink less water" as part of desert training is valid should really show who's the one who knows nothing about desert operations here. Really, you'll learn more about how to operate in a desert more by watching
Jarhead (with its hydrate, hydrate, hydrate some more montage) than anything the Germans came up with for the Afrika Korps.
