What is the seven-man grunt rush?
It is a devastating strategy for medium-resources land games. Build a hall, three farms, and a barracks. As you do so, produce six peons or peasants. Start the barracks as soon as the first farm is done. Set five peons or peasants to mine gold, and put the sixth to chopping wood. Use the gold to produce seven grunts or footmen. As you produce them, scout for the enemy. When you have all seven, gather them outside the enemy town, then attack to kill all the enemy peasants or peons. If this doesn’t work, you will eventually have enough wood to build another farm, produce more choppers, and proceed as usual. This strategy is so nasty that people rarely play on medium resources any more.
