Errata for Sinister Forces "Armored" trains?

[Mmookk61]

Good day all.  I have a question on the unarmored "armored" NKVD trains in the supplement Sinister Forces.  The two NKVD train counters do not have an armor value printed on the counter.  Which should I assume: 1.  They are indeed meant to be soft targets.  or 2.  Should they have a normal armor of 2 as do the armored trains in Eastern Front Deluxe?

I checked the scenario listing for Sinister Forces scenario #9 and it does not list any kind of errata for the train rules or counters.  I have asked this on the Facebook group also but is there any "official" officer that can sign off on an answer?
