Sure, you can post sentries, but the smart opponent will avoid them as soon as he or she sees them. Red Alert-style fog of war makes posting sentries unnecessary, but people often complain that this style lacks realism and makes ambushes harder. However, I think that the advantages of this kind of fog of war outweigh the disadvantages. Ambushes are not really removed from the game. In Starcraft, the Zerg burrowing ability could still allow ambushes.
Cloaking units can also help out.
Even without burrowing or cloaking, just because your units are not hidden from your opponent, it is not necessarily true that he or she will see them. Maps are big, and it s very difficult to keep an eye out for enemy units. There is not really a superior fog of war style at this point, and perhaps the Starcraft style will turn out to have more potential than the alternative, if line of sight technology is perfected and the site range of units is increased for realism. The point is that neither idea is really better, and if it sounds like I favor the Red Alert style, it s only because I liked Red Alert so much. Contact us .
