With these Multi-National Force Structures it is hard to say. Could have mix and match units. The unit designations were given by voice to the person who composed the email. The main question if it was the new Stryker Cav unit, is why were they assigned to the 10th Mountain Division ? Perhaps a logistical assignment. They were a new type of unit. Combining Cav personal with the Stryker.

They were a new type of unit. Combining Cav personal with the Stryker.

And from the looks of it they were originally with the 2nd division, then with the 25th, so I guess 10th Mountain's also possible.
