Not yet, but some of my friends have. And I have some interesting "artifacts" from the war. The most interesting is a circular circuit board, designed to fit inside a sewer pipe. It has a radio receiver/detector that detects a combination of 2 audio carrier tunes, and after receiving that special carrier (from, let's say, an airplane with a suitable transmitter that flies past, it counts down for one week (suitable time period to make everything untraceable / deniable) and then issues a detonation signal...

Seems teh argentinians left a bunch of them in sewer pipes, along with a fair bit of TNT...
