Iran isn't just central Tehran. Look up the Zagros Mountains and the Alborz Mountains. Or just look at a picture of the northern Tehran skyline, it is at the foot of the Alborz, a huge mountain range. There's plenty of woodlands and forest too. Some parts of the Hyrcanian forests get over 50 inches of annual rainfall, which isn't Forks, WA, but it is substantial.

You'd get additional specific training for deployments and the skills are transferrable. But obviously they can't train everyone in every biome that we have, otherwise you'd spend a whole year just flying around to different areas of the country to train and on a 4-year contract it's just not going to work time-wise.

Sounds like typical one-sized-fits-all, checkbox military nonsense. Perhaps there are better and/or climate-specific SERE courses in one or more services? Because if it's ineffective, it's a waste of time and money more so than usual and puts expensive-to-replace personnel at risk.

Seems like it's all about vacating the area and busting out the CSEL (or NGSR when materialized) personal SAR comms is the best way out, or it may well turn into a weeks(s) long, nonstop spy-shit ordeal getting out. Perhaps some forethought and packing with knowledge and specific local-appropriate items (and chunk of cash) would help more than MIL-STD Walmart camping aisle prepper bullshit.
