US Military: Operation Urgent Fury (1983).
After Vietnam, for the US Military & the Commander in Chief it was keep a low profile and don't provoke something that would require the deployment of US military forces. And if & when it became necessary to deploy military forces...do it quickly, cleanly, and don't tell anybody (censor the news) unless or until it is a successful campaign. That time came when President Reagan commenced "Operation Urgent Fury" in Grenada in 1983. The first use of offensive US military force since Vietnam and it was a success; but the news people complained about not knowing about it before hand...which is possibly why it was so successful. For some semi-factual entertainment on the campaign in Grenada see film: "Heartbreak Ridge" starring Clint Eastwood. This movie is about Operation Urgent Fury.
Ronald Reagan used combat forces abroad. Reagan deployed Marines to serve in the Multinational Force in Lebanon in 1982; these men were killed in the Beirut Embassy bombing in 1983. Reagan also deployed combat forces to Grenada. Also in 1982, Reagan began supplying US forces to the Multinational Force and Observers mission in the Sinai. Gerald Ford was the only president in recent history to not deploy combat forces abroad.
Gillian Bristol is the Ambassador to the US for Grenada.
