Schuler,
thank you, thany you very much: you're really inside the editor mechanic!
You're completely right about the ammo: the problem IS NOT in the Faceplant model, in effect first I tryed to change the civilian with those by FML and those units too started the preview with the "Out of Ammo" message.
Then, I followed your advice, and inserted the command
removeallweapons this ; this addmagazine "MP5A4mag" ; this addmagazine "MP5A4mag" ; this addweapon "PM12"
givin' TWO magazines before the GUN and... POOF! the unit started wih a "Ammo Low" message and 2 magazines available (if I make them drop the gun, I find now a gun with two magazines).
Problem resolved with you kindly help, it appear the the PM12 need more than a magazine in the init field to load the weapon: now I will experiment with the right magazine number to correctly equip the units.
Thank You again, and I apologize for my noobiness, startin in the y2007 a game so old but so realistic!!
Bye,
Toante
