At Norwich University in Northfield, students are being taught to fight the war of the future.
The mock battles are on computers. Students are learning to protect communications networks from cyber-attacks.
Such cyber war games are well-established between schools in the United States. Norwich has added a new twist: One of the other teams is from Macedonia and another from Oman.
This semester is the first time Norwich is working with the overseas schools.
In a six-week seminar nearing its end, students take turns building and defending computer networks, attacking one or monitoring the operation.
Norwich junior Jacob Evans of Tuftonboro, N.H., says the international war games add an element of authenticity to the process.
