Missile weapons come in two varieties with different sizes denoting the number of missiles fired. Short Range Missiles (SRM) offer high damage and knockdown ability at close range. Long Range Missiles (LRM) offer indirect fire over hills and mountains at great distance. Both types need ammunition, specific to their type, but not size of the launcher. One LRM ammo bin can feed all LRM launchers on the mech, regardless of size, as long as enough missiles remain.
