I saw a WW2 era filmclip where an Afrika Korps tanker fried an egg on his Panzer's hull. Those guys seemed to have performed adequately though. It's not so humid in the desert at least.One of the more stupid mistakes of the Indian Army which hopefully, they will fix. As I mentioned earlier, power derating was cited as a reason for not purchasing/deploying the ACs, but as is obvious- the AC need not be on all the time.
