The news media in general has a liberal agenda, and what they print is the means to an end, ie, a more liberal government.
I would guess that the media would hate any source of news that differs from their biased opinions.
The report these numbers comes from can be found here:

If you look it over, you’ll get an idea of why the numbers are they way they are.
For example, in 1980, when the report starts, there are a total of 2392 fatalities. This includes deaths from accidents (1556), deaths from homocide (174), deaths from illness (419), suicides (231), hostile action (none), and terrorist attack (1). Also, at that time, the active duty strength was a little over 2 million.
In comparison, in 2006, total deaths were 1858. This includes deaths from accidents (465), deaths from homocide (30), deaths from illness (205), suicides (155), and hostile action (753), with another 250 not yet determined. Also, at the time, the active duty strength was a little under 1.4 million.
