I got really board and had nothing else to do so I took a ammo box and started to paint it.

I'm going to put the ammo and weapon info on the other side, but I don't know which weapon to use.
I painted the front black, then I put a stencil over the black and painted over everything with green paint. And to answer the first question, yes I printed a picture of the logo and cut it out.
I have one too. It is a WWII box. I have looked at the impressions under the black paint that proves that My box used to hold some flares. But then again, this is HALO!!! Let's paint the unsc symbol on there and then say It holds ammo for grenades, Assault Rifles, Battle Rifles, Etc.
