One of the most important roles in Allegiance is that of the interdiction player. While most of the team is off bombing bases and harassing miners, someone has to keep things safe in the home sector. Though much of a teams defense is determined by the commander, I want to focus on the individual players role.
Defense begins at the end of the countdown.
As the offensive wings are loading out scouts and finding alephs a defensive player should start off with a scout loaded with mines and missiles, depending on your skill with mines, you might choose an energy weapon instead of a gattling gun. You might also load more mines and missiles. The first order of business is to make sure constructors and miners get where they need to go safely. Usually two to three players will guard each constructor unless the enemy team is engaging in a scout rush. Defending against the scout rush is a complete tactic guide in itself.
