===== Weapons Free =====

Prior to the first release after R2.0SR2.30DTRA, weapons free had been a binary value by side -- weapons were free or they were not.  The default status of weapons free is stored in the firingPolicy instance variable in the JwForceGuidance object. Each side has its own JwForceGuidance object.
More recently, firingPolicy was changed so that it will hold one of four values:
  - JwFpWeaponsFree 'Weapons Free' 
  - JwFpWeaponsTight 'Weapons Tight' 
  - JwFpWeaponsFreeChem 'Weapons Free - Chem Authorized' 
  - JwFpWeaponsFreeBioAndChem 'Weapons Free - Bio and Chem Authorized' 

The message weaponsFree now returns true if firingPolicy is not equal to 'Weapons Tight'. Default firingPolicy can be set in the Wmd gui. Firing policy can be changed through the Knowledgebase for an entire side or for a specific Bse or for a specific Bse and all its subordinates
