What is this? Maybe WW2?

I found this at a military base that was active from 1930-1980, it is made of cast iron, I put a Gatorade bottle next to it for size comparison, what do you think it is too? I also found it next to a bunch of cartridges.

Thanks!!

Some sort of expanded metal subway grating?
(Perhaps decking, or part of a walkway?)
