The Maginot Line - A misunderstood history

Canon de 25 AC

Light anti-tank gun

There were two versions of this 37 TRP: the SA Mle 1934 and the SA-L Mle 1937 Puteaux. Puteaux is often replaced by APX (Atelier de Puteaux). The 'L' standing for Légere (lightweight).
Both guns were the same, but the Model 1937 had a lighter carriage (total weight was approximately 300kg as opposed to 480kg of the Model 1934), and the barrel was slightly longer.
The three photographs in the right hand corner are of a SA-L Model 1937, the AT gun in the video is a SA Model 1934.

According to French and German sources, the muzzle flash suppressor combined with the gun’s low profile made them difficult to spot during combat.
The 37 TRP guns proved to be very accurate, able to destroy all German tanks up to 800m if the angle of engagement was good enough Unfortunately, the 37 TRP’s armor penetration capability was already limited by 1940 when engaging the PzIV Mark D at long range.

In 1939, the British Expeditionary Force had insufficient numbers of anti-tank weapons. Therefore, they were issued about 220 Canons de 25 to strengthen their AT capability. In exchange the British gave the French some Boys AT rifles which were not efficient and had a weaker penetrating power than the Hotchkiss 13,2mm.

The Germans captured the 37 TRP in large numbers in 1940 and later used them insecondary roles as coastal defence and in some garrisons. The SA Model 1934 was known under the designation 2.5cm Pak 112(f), the SA-L Model 1937 as the 113(f).
Finland also made use of these guns.

Additionally, the US Army purchased some in 1935 for evaluation purposes. One of these guns may be in the video below.
