Video I edited from the late 1960s U.S. Army’s The Big Picture film to focus on the M109, and a sneak peak at what was then the experimental M109A1 (complete with fake artillery sound effects):
Another video I edited from The Big Picture about the USA 3rd Armored Division in NATO Germany, late 1960s, showing the short barreled M109 (there was no nat-sound, and the narration is terrible so I edited it out):
Silent USA film by ‘Jensen’, M109 action Khe Sanh area, Viet Nam, August 1970:
With the M109A1, the short M126 barrel was replaced with the long M185 cannon. From A1 through A4 series there is no visual difference, the upgrades being internal. If you’ll notice, some photos show a protruding panoramic periscope, while others do not, and it does not matter if it is an A1, A2, A3 or A4. The A5 variant got a more powerful motor, and a new M284 gun of apparently the same length as the M185, visually similar to its predecessors.

In the mid-1970s, the U.S. Army (USA) turned a M108/109 into a fake-news ZSU-23-4 for use in the testing of a U.S. Air Force (USAF) ground vehicle identification/targeting program. It was seen again, very briefly, in a ReForGer (Return of Forces to Germany) wargame, where European tank-o-philes speculated that the USA had created a new anti-aircraft tank.

In 1984, the U.S. Army (USA) announced it was considering an ‘A5’ upgrade to its M109s, and the creation of a specialized ammo carrier based on the M109’s chassis. There is very little visual difference between the earlier long barreled M109s and the ‘A5’ M109.

Amazingly, this obvious M109A6 Paladin was listed by ‘officials’ as an M109A2!!! In fact, a whole series of photos showing Fort Carson, Colorado, M109A6 Paladins are listed as M109A2s! Also, notice this Paladin has a Mark-19 40mm grenade launcher in place of the usual M2 HB .50-cal machine gun. The A6 has a new turret, gun mantlet and even new style gun travel lock.

LATVISKI M109A5Ö (THE Ö IS FOR ÖSTERREICH)
By 2019, a new, so called, M109 began arriving for duty with the U.S. Army (USA). In 2021, Army National Guard units began getting their new ‘M109s’. Many military armchair ‘experts’ who get paid to write articles for military themed journals call the ‘A7’ an “upgrade” of the A6. I do not consider the new M109A7 Paladin to be an ‘upgrade’, nor do I consider it to be a true M109 as it uses a completely new hull/chassis that is based on the M2 Bradley Infantry Fighting Vehicle, as well as a completely new gun system.
Even in 2021, U.S. Department of Defense media personnel still get it wrong! This video, posted on 09JUN2021, shows Royal Moroccan M109s, obviously the A1 through A5 type, yet it was labeled as “Royal Moroccan Armed Forces Paladin” (the A6 is the true Paladin).
