During the Falklands war, the Royal Marines were sent to the South Atlantic in their autumn. They had just come off winter training in Norway and still had all their winter gear. A lot of the Argie soldiers were drawn from some of their “jungle regiments” who’d been in garrison along Argentina’s northern border with Brazil, Paraguay and Bolivia. When they got to the theater, they still had their jungle kit and were totally unprepared for warfare in those inhospitable latitudes.
If the Brits had decided to get nasty they would have taken the war to the mainland and knocked Argentina back to pre-electrical times.
I'd personally like that to happen to Chavez and the rest of the tin horn, Castro wannabes.
