Again, I agree with Monk. USSRSniper, you seem to have little or no experience with the military; it isn't all about firing a gun, as combat isn't exactly like a foxhunt in a forest somewhere in Wiltshire. Soldiering is about tactics and fieldcraft. Fieldcraft is difficult to train with a simulator, yes, but navigation, and more importantly, infantry tactics can be taught and trained effectively. VBS2 isn't a substitute to conventional, practical training, but rather a supplement. It's engine is tweaked to allow observation and recording, and has been tailored for military use.
Fire and movement, contact drills and other tactics can be practiced in a safe, cheap environment allowing the recruits to concentrate on the elements themselves, and can train more dynamically without having to mobilise a regiment for training.
Young soldiers may only have X weeks of basic training and infantry training before they go to Iraq or Afghanistan. VBS2 can make them more confident in their abilities, and can also start adapting them to the environments they will be working in, since maps are realistic recreations of various areas of operations.
And finally, VBS1 and 2 are not games. They're training-tools developed for the armed forces, not for the consumer. Bohemia Interactive Australia have chosen to make them available to the public, but they're clear about what their products are; simulators.
