I think adding more compositions to the construction truck cool be nice.
- crates : either empty to place yourself the stuff you want or preset ( grenades, ammunation, rockets )
- Static weapons alone : its cool to have sandbags, barbed wire etc. But sometimes it take too much space, so having the weapon only that you can place would be interesting.
- anti blast shelters : or whatever it is called, mortars will be a game changer, having some way to shelter from the shelling would be fantastic.
Any other thing would be nice too. I like making FOB or defense points.
