What's that supposed to mean? You linked their marketing material to the 250. Below is a link to their marketing material to the 300 and another to the 70 series.

I am sure TGS happily sells 250s, 70s AND 300s to the UN based off the same marketing.
There is nothing about the 250 being the preference. Actually, a quick search will show that the preference is for the 70 series - for obvious reasons.
In terms of the military, I am sure we have several enthusiasts here that served our country and will readily tell you which vehicle they saw the most deployed in overseas ops.
