I learnt the names of every wood and all the villages, I knew the contours of the hills and the shapes of the lakes in the valley. To see so much and to see nothing. We might have been the only men alive, my two signalers and I. And yet I knew there were thousands of hidden men in front of me ... but no one moved, and everyone was waiting for the safety of darkness.

After 40 minutes of Combat Mission PBEM simulated combat against my friend Olav, I feel the quote above puts it very well.

The modern battlefield is a very empty one.
