Something looks off about the helicopter on top too. I’m sure they rolled out thousands of these mats with all kinds of variations, some with decoy copters, some with painted copters clearly not matching the shadow (so actual-copters can land there). We’ve seen their elaborate decoy setups so this would introduce another element of decoy-ism, and make it harder to know when real things are/aren’t there.

It also looks elevated, either higher on the right or higher on the left side but that could be my eyes playing tricks.
