Also Barnacle Bill, it isnt 10 tons of ground troops, its 10k tons, which is 10000 tons...

Right - my bad.

However, here is more about my point...

The maximum population of a large world (i.e. default player homeworld) is 4000M. Given that the Earth currently holds roughly 6 billion, 1000M can't represent less than 1 billion people (or whatever). In other words, it is safe to assume that "M" stands for "Million" so 1M of population = 1,000,000 people (or whatever). 1M population takes up 5kt cargo, and a small troop takes up 10 (at starting technology). In other words, a small troop takes up as much cargo space as 2 million people. So, if a troop is a single vehicle it's a mighty big one.
