It's durable, reliable, accurate out to 42 miles, there are thousands in service which means there are plenty of spare parts - and lots of available ammunition, making it a kind of heavy artillery version of the AK-47. JL
Sofrep reports:
Western allies have supplied Ukraine with 50 M-109s, more than any other 155mm NATO-standard self-propelled gun given to Ukraine up to now. The first M-109 used in the U.S. in 1963, (but) updated versions are still being produced. Hundreds of second-hand units are available, which makes it a good option to reinforce Ukraine. Its maximum range extends to 42 miles and is noted for its reliability and abundance of spare parts. The M-109’s reliability and suitability for the task instead of more modern tools ensure best outcomes.
