An interesting, if general, article in Strategy Page describes some recent interest in naval wargaming by the Mexican Navy, inspired by exposure to USN naval wargaming, presumably at the Naval War College.
While US wargames rely heavily on computers, the article indicates a larger role for manual wargaming in the Mexican case. Given the kinds of threats the Mexicans have to cope with -- mostly drug cartels -- this seems appropriate. It's not like the Mexicans ned to track the activity of large fleets of ships, armed with clouds of missiles and backed by squadrons of aircraft like some NATO-Warsaw Pact confrontation might involve.
A more hands-on, creative and intimate approach by manual wargames would seem much more useful, I think.
The article doesn't mention any specific, but it does make me wonder if some version of the commercial Harpoon4 rules has found its way into the Mexican Navy's toolkit.
