trouble with supply trucks

[RHYS4190]

i find it a bit of a joke that all the supply trucks i seem to be able to get are chock full of Arti rounld which im not using.

and has very little small arms ammo 500rds of rifle ammo/ which is a joke you should have 10 times that ammount/ im litrally only having enough ammo to supply one squad which keeps them going for 5 minites/



is there a way of changing the values for the trucks so they have a much bigger supply of ammo?
