TEC for Airborne IE

[triangular_cube]

The general understanding at the time was that the TEC on the scenario book for swamps was misprinted and you should use the values on the 3rd edition TEC. (A:IE was the first module published with 3rd edition btw). Hedge rules/TEC should be correct in the scenario book. I would have to dig up old CSW posts to cite that, but I read through it all again last fall when I was prepping to play the module "properly". 

Most people retcon 4th edition into the older games, so I don't know what they would tell ya.
