Look, there's living witnesses to this. You can write up all the maintenance papers you want. It's not like they're time stamped and put into a hermetically sealed jar, in a vault, in the middle of the desert for future reference.
It's a miracle that there were any survivors!! Kudos to their rescuers.
The Army has already done a report based on interviewing all concerned that seems pretty accurate by comparison to the public information. It's the families who are claiming a cover up because the maintenance logs were lost in battle. Some in the unit are trying to blame defective equipment, but there isn't any support for that either.
I'm not critical of the soldiers, who responded the best they could when attacked. I am somewhat critical of the commander who got them into that pickle, however.
