Mexico has made
significan strides towards becoming a first world nation, and it's
military is just one example. The largest independent military
force in Central America, and the best equipped, the Mexican military
protects the country from all threats foreign and domestic. The
police department itself is merely a specialized branch of the
military, with all police officers required to spend a year in
regular service (basic military training package, see Home Of The
Brave) before they are eligible for police duty (non-combat skill
package, see NCPD).
Due to Mexico's practice of isolationism during the last war, the
Modern Mexican Military is untested, save for border patrols and minor
incidents, however no one takes them lightly as in the few minor
instances they have had to face they have acted with expert efficiency
and brutal skill. 
Another factor that aids them is their growing self
reliance. While Mexico still buys and issues some russian and
chinese surplus, particularly for vehicles. The companies of
AZTECH and Mexican Metals are getting more advanced every year, and
have reached a point where home manufactured weapons and equipment are
the majority already. Aztech in particular has very quickly
become one of the leading manufacturers in the world. 
The rank structure in the Mexican military is virtually
identical to that of the United States, even among the police branch,
though the pay is about half that of the North American counterpart.
