US Armored cavalry Troop in Vietnam Official Table of Organisation and Equipment (TO&E)

ARMOURED CAVALRY - Page Title
TROOP MTOE 17-107E


The Armored Cavalry Troop consisted of a Troop HQ (HQ Section, Ground Surveillance Section and Maintenance Section) as well as three Armored Cavalry Platoons.

I have also provided a summary of Personnel and Equipment as well as some Notes regarding the differences between the 'official' and 'unofficial' MTOE's.

If you have any comments or suggestions regarding the material presented here then please contact me. In particular if you served with an Armored Cavalry unit whose MTOE was different from this or different from that given under Composition of US Armored Cavalry Troop then I would like to hear from you so that alternative information can be provided.

NOTES

There are some very important differences between the official MTOE (presented above) as stated in Special Text 17-1-3 and the field organisation adopted in RVN. Principle among these are the use of ACAV's in all slots filled by an M113, except for that of the 4.2-inch Mortar Squad . The effect of this is to significantly increase the fire power of the Troop.

Also note that the MTOE refers to 7.62-mm rifles (both Automatic and Semi-Automatic). These were replaced with the 5.56mm M-16 and the 7.62-mm M-60 MG.

In the MTOE above, many of the positions are assigned a pistol as the only personal fire arm. In RVN all the members of the troop carried an M-16.

The 1/4-ton utility trucks were invariably base camp only vehicles. For instance, in the Troop Headquarters Section, the CO is officially assigned a 'jeep' but in reality only ever went to the field in an ACAV.

Please note that the MTOE above is significantly different from the organisation given under Composition of US Armored Cavalry Troop which is based on the organisation of 'B' Troop, 3/4 Cavalry 1968-1969 according to Jerry Headley and Stanley Homiski. In this sense, the organisation given by these Veterans is that of an actual Troop in the field where, in most instances, TO&E's were greatly modified in accordance with the requirements of active duty.

See also US Radio Communications and US Radio Equipment for an explanation of Troop radio communications.
