Reading the book about firebases in Vietnam, it mentions how the M102 howitzer was used in them. But said howitzer has a later version used in other wars up to the first Gulf War, and I haven't been able to find any information as to how it was deployed and used since Vietnam.

The M102A1 howitzer was the main light towed howitzer of the US military (mainly Army, USMC kept the M101A1 as their light howitzer) post Vietnam up through the early '90s when it was replaced by the M119 105mm howitzer. It was a little different and had an added triangle piece just in front of the recoil cylinder on top of the barrel. It is an additional recoil part that reduced recoil further. This piece is also in the AFV Club kit and it can be built either as a Vietnam M102 howitzer or a later M102A1.

You can see the added part well in the below Desert Storm pic.


It was used by all US Army light units. Like stated in your earlier post, the M35 was originally the prime mover for it until the HMMWV was fielded in the early '80s. At that time, the HMMWV became its prime mover. They were organized in 8 gun batteries with two 4 gun platoons. Usually, the battery stayed together and moved from firing point to firing point as a unit in convoy. They could also be moved by air for a raid forward of the US line of troops.

A few examples.

Granada, 82d ABN, '83. These are still M102s w/out the added recoil part. In the mid-late '80s, the M102A1 was fielded.





82d ABN training, '89. These are all M102A1s with the added recoil part.

From memory in 73 war the israelis flew a couple deep behind egyptian lines with ammo, fired off a bunch of rounds at unsuspecting egyptians and the fly back again, cant remember the name of the operation but will find it.

I will amend slightly my brother Gino's information, especially as a post Vietnam M102 battery commander. The M102 was deployed with 82nd AB, 101 AB, 173 AB Brigade and 10th Mountain on active duty,in reserve the 187th Brigade and and 2 national guard battalions existed. All other 105mm units were M101A1 units.

The roll bar was used by the AB batteries. The other units did not use them. The 82nd and 101 used a Goat as prime mover while other units used M35 2 1/2 ton trucks. The goat was replaced by the HMMWV but the duce stayed in the other units.

The M102 never really was issued the designation A1 but the changes were made around 1990 as an interim change until the M119 was deployed. These changes were seen on the M102 which were deployed with 82AB and 101AA as part of Desert Storm.

After the mid 90s the M102 was redeployed to the NG once the active units all received M119s. There were some M102 deployed to Iraq early on with National Guard units.

To my knowledge, though the US Army experimented with the 3 x 8 battery concept, in the early 80s, none of the AB or other M102 units were organized in the matter.

Further, the upper carriage and gun are mounted in the back end of the AC130 to give that plane its 105mm firepower.

Great info as always Mike. Thanks for the assist. M102's were pretty much gone by the time I came on active duty in '94. There were a couple M102s as salute guns at Ft Hood and Ft Stewart. We trained with M119s at OBC.

I still had a pair of them for training maintainers in my maintenance school from 2001-2005.

Thanks everyone!

BTW at the National Guard base on Cermak Road that I referred to before, there is an M102 on display in the green camouflage colors and no roll bar on top. For some reason the barrel is in unpainted aluminum. I'd take a photograph, but am not sure if I am supposed to or not.

The M102 had some certain advantages over the 105's used prior. Besides the fact they were easier to transport by air, they were easier to setup. In Vietnam you shot 360 degrees, and usually found yourself in the middle of everything. Previously you had to assemble a parapet. Similar to what a 155 used, but a little smaller in diameter. Plus the recoil was much less. Moving to an LZ that had 155's prior meant six new parapets or reworking the old ones. Once the gun was laid, the centerline stayed in place unlike the old guns that displaced on the first round, and continued to changed because the gun didn't set on three points like the 155. Just a little more accurate down range. Still the real plus with the M102 was high angle fire! In the mountains this was almost the norm. You always kept at least one gun setup for high angle fire to get deep into the valleys. Yes you could do this with the old gun, and trust me it was never fun. And the early gun was easier than the bigger guns.

The M102 were also used by Light Infantry Divisions like the 25th ID. and the 29th Inf Bde in Hawaii. I seem to remember that they were towed by M561 Gama Goats.
