hi all guys!
sry to revive this, but thats more or less what i need!
i wish to make some vehicles (that can be destroyed and in that case will respawn) with a virtual arsenal always enabled....on DEDICATED server (my biggest troubles were about make it work in MP/ dedicated)

lets say i have my helicopter named "BLUhelo1" (with virtual arsenal already active).
it gets destroyed, but being linked to a respawn module, it resurrect.
to get it has its virtual arsenal again, i added this line in the respawn module expression field:

["AmmoboxInit",[BLUhelo1,true,{true}]] spawn BIS_fnc_arsenal;

and seems working!

hope this helps other people in my situation!
