I remember reading that when the Clans first showed up, their tactics were so radically different, they though the Clans were aliens. Just pointing that out.
So what is everyone's favorite weapons in Battletech/Mechwarrior? Pick one close range, one medium range, one long range.
Close: Melee or Machine Guns.
Long: Autocannons. Banks of UAC2's I find to be highly effective and very very efficient. Not really a missile fan.
