Dunno if still works,but ammo script,and markers was working fine,i used other script besides of these 2 ,that was dected,so my arma 2 is now in graveyard.But today will buy new one with original key for 11 $.
But i have something interesting,didnt tested but maybe this will do trick.
Since all Dayz are global connected and player items,weapons... are recorded no matter in wich server you are,so try this:
In Arma put filters without BE,go on server,spawn what ever you like.Lock and load,back to server you want and tada.
Like i say i m not sure if this method will work,but you can try
Cheers
