Old Sarge,
Unfortunately this “Iron Horse” is 1st Bn, 8th Cav, 1st BCT, 1st Cavalry Division from Ft. Hood. It is a combined arms battalion with 1 tank and two mech inf companies.
Others have thought it was the old llth ACR squadron, but alast, it is not.
Additional info:
The unit is 2nd Battalion, 8th Cavalry. https://www.facebook.com/pages/2-8-CAV-1BCT-1CD/130679013617883
2-8 Cav in 2002 was organized as a tank battalion.
I found a posting that it is currently a “combined arms battalion”. If it is deploying with only 20 Abrams tanks, then it must be organized as an infantry battalion heavy “Combined Arms Battalion with 2 infantry and 1 tank company.”
See: http://en.wikipedia.org/wiki/Brigade_combat_team#Combined_Arms_Battalion
Right now the Army is in the midst of cutting units and re-organizing units to meet the bh0 cuts to Army strength.
When I was in the old 3rd Armored Division’s Divisional Cavalry Squadron, 3-12 Cav, we had 36 tanks (M60A3), 12 per troop, 50 x M113s & ITVs and a 4 M577s
the traditional divisional cavalry squadron has been replaced by the Reconnaissance, surveillance, and target acquisition (RSTA) battalion. It does NOT have the combat capability of the Cold War ear divisional cavalry squadrons.

Also, the 1st Cavalry Division, in which I also served, the battalions were traditionally organized as either infantry or tank battalions and were named “cavalry” to keep the lineage and honors of the old cavalry units alive.
