Now since a troop is by definition a group of people, "more than 100 troops" would be at least 202 soldiers (101 being more than 100, and 2 being the minimal group), and -2 others :).

Speaking of weird units of measure, what happened to permille? Does really nobody know what it is? Why do they always say the rate has increased by "two tenths of one percent", but never ever say which percent is that? Just "one". Is it the same one each time? Why is it never "zero point two percent", or "two tenths of a percent" or "a factor of 0.002"?
