We tagged along with the Brownells crew to the Texas Hill Country to visit Ox Ranch and Drivetanks.com and fire a WW2 era M2A1 Howitzer! These towed artillery pieces were the workhorse big guns of WW2 and several later conflicts. Capable of firing a variety of different shells for various mission requirements, they are extremely versatile, reliable and effective guns. Stay tuned, much more on the way.

Cool thread.

What does this tube do?

M119 howitzer still plays critical role for Army
https://www.army.mil/article/155135/M119_howitzer_still_plays_critical_role_for_Army/

From the article:

RECOIL SYSTEM COMPONENTS

The M119 howitzer's recoil system consists of a recoil brake (a damping system) and a hydropneumatic recuperator (a gas spring system). A recoil system's main function is to absorb and control the rearward movement of the cannon and return it to its original firing position, thus avoiding violent shock to, or movement of, the carriage.

The buffer, the damping aspect of the system, absorbs the reaction forces of the firing howitzer and brings it to a controlled rest within a determined length along the sleigh, the part of the carriage that provides immediate support for the howitzer tube and houses the recoil system. The recuperator, precharged with gas, uses the rearward movement of the cannon to increase its gas pressure, creating the energy to return the cannon to its original firing position.

The redesigned system modifies and simplifies some of the components, but operates on the same fundamentals as the legacy system. The new design modifies the buffer by splitting the front head of the legacy buffer into two pieces, compensating for potential misalignment within the system and internal recoil length. The redesigned recuperator is a modified version of the legacy version with a majority of the components removed.

This is possible because of the Suspension Lockout System, or SLOS, and fixing the recoil length at 25 inches. The SLOS is an easily installable, field-deployable device used to stabilize the M119 during high-angle firing. It removes the problematic variable-recoil hardware, and works in conjunction with the fixed recoil system to reduce accelerations and stresses on the carriage and lower buffer rod forces.

In the legacy recoil system, recoil length varied from 14.5 inches to 42 inches depending on the elevation of the gun. The combination provides more stability by reducing platform displacement, resulting in more responsive fires and making it safer for the Soldier to operate.
