While I can see, now you've mentioned it, an Easter Eggyness to it, it does look right. As for T72's they have many variants and there are within the game a few icons which pretty much cover them off for the scale here. I'm positive the T72 you saw looked different than the one here especially from a ground prespective.
Bottom-line don't worry even after playing this game for 15 plus years I'm still seeing things that I'm assured are not there!!
