That Stalled Convoy

 Like many of you, I've seen pictures of a military convoy north of Kiev.  By all reports, it contains fighters and logistics (bullets and beans) for the army.  Yet, it appears stalled along the road .  Why is that?

Commanders know that combat absorbs supplies at a pace that would astound neophyte observers.  Armies on the move require huge reserves of fuel,  ammunition,, food, and manpower.  The commanders job is to push those supplies to where they are needed, yet that convoy seems to be stalled on the road.  So, is it lack of will on the part of the local commanders?  Or is it equipment breakdowns?  Or is it sabotage?

Or is it the tires?

Bit of a tire expert here. Those aren't Soviet-era heavy truck radials. Chinese military tires, and I believe specifically the Yellow Sea YS20. This is a tire I first encountered in Somalia and Sudan; it's a bad Chinese copy of the excellent Michelin XZL military tire design.

That might be one explanation as well.  Bad tires. That may be part of it, but I an getting a sense that the troops aren't committed to this battle, that the rank-and-file may be slow-walking this thing.  

The Russian commanders on the ground have a much tougher problem than they envisioned when they set out last week for a glorious cake walk through Ukraine.
