For this application hydrogen makes more sense.

    Yeah I thought the same thing, but no. People who actually launch weather balloons swear off hydrogen like a plague, because apparently it explodes while you are filling the balloon.

    That makes sense, although in wartime it would matter less. You can also generate it fairly portably with ferrosilicon and acid.

    It's worth mentioning a football field or whatever of Mylar won't be free. Big balloons retail for hundreds on their own according to a quick search.
