I would suggest using a WaitCommand in a CommandGroup. Below is an example that will fire, then wait 1 second before firing again and then finishing the CommandGroup.

public FiringCommandGroup extends CommandGroup {

     public FiringCommandGroup() {
          addSequential(new FireCommand());
          addSeqiential(new waitCommand(1));
          addSequential(new FireCommand());
     }
}

Another way to do it would be to check the time passed in the execute method of a command to see if the period of time you want to wait has passed.

Commands also have a timeSinceInitialixed() method that will return the time in seconds since the command was initialized(aka started). This could be used to check to see if a command has been running for a certain period of time.
