Reference shots.

trying to figure out what's stuck in between 3rd and 4th roadwheels. it might be something outta sheet metal just as well considering a 70something tonnes of mbt not giving a flying f*** about it and driving around happily.... 🙂 or it's simply a piece of tarp or bigbag/sack kinda tensile enough fabric/textile.

how can it remain there is another question of course. maybe it's actually stuck around the sideskirt holders, if there are any available on the abrams. 

caked mud and damaged mudflaps as well as trackpads.

light blue grey markings. 

dried mud on the sideskirts (it's pretty visible when the curves of pic is amped with an imp) vs. fresh (or mixed with jp7) mud on the back, in conjunction with the previous pic.

also note the smoke dischargers and the rope around it as well as what looks like a barbed wire hanging at the back. plus the dislocated tow cable front section on the turret.

as for the light blue gray markings on the sides, no idea what they are nor does dragon provide those... any help is appreciated.
