Playing on XB1 NA-East, Map Ghost Town, Game Mode Assault and not platooned.
Spawned inside of a building (granted a partially destroyed one) that would have had no way into without destroying it or it being built around the tank after parked.
Grid and map location:
From inside of building at start:
Hope this was enough information. Though not a big issue things like this do hurt the immersive nature of the game experience. As a side note maybe a pinned thread for strange spawning might not be a bad thing. I since 3.5 have on Overlord been spawned facing the back line, partially on top of other tanks, in water (drown counter going at start) and the funnies on my side flipping after the flip correct. If these are happening to me I bet they are to others and maybe not being reported.
Thanks for your time,
