Hotchkiss Mle 1930 (13.2 mm)

Description

13.2mm Hotchkiss Mle 1929 in Naval quadmount

The 13.2 mm Hotchkiss Mle 1930 is a French-built heavy machine gun for multi-purpose use. Starting as the Hotchkiss Mle 1929, the Mle 1930 is a ground-based anti-aircraft designation of the machine gun. It is commonly used as close anti-air defence by the French Navy and also by the Army during the '30s until WW2. The guns was also adapted as main armament for tanks, armoured cars and anti-aircraft vehicles. The Hotchkiss was for France the equivalent of the M2 Browning heavy machine gun.

Vehicles equipped with this weapon

• P.7.T AA

General info

The 13.2 mm Hotchkiss offers balanced performance against aircraft and soft targets, but has difficulty against vehicles with more than 20 mm of armour. It is fed by a 30-round magazine, which leads to the weapon's limited capacity to sustain suppressing fire. The gun has a fire-rate of 450 rounds per minute, but in practice it would seldom reach 200 rounds per minute due to the reload and recoil.

Available ammunition

Only one belt is currently available for the Hotchkiss in the game, the AP-T belt.

Comparison with analogues

• M2HB (12.7 mm) - Similar gun in performance, but a lot more successful. It replaced the Hotchkiss 13.2 mm after WW2 for standardization purpose.
• Type 93 (13.2 mm) - Japanese licensed copy of the Hotchkiss
• Breda Model 31 (13.2 mm) - Italian licensed copy of the Hotchkiss

Usage in battles

This armament has a relatively small calibre which causes the post-penetration damage to be rather low. In many cases, even a direct hit to the crew might not be enough to knock them out. However, the 30-round magazine and fast fire-rate allow the user to place multiple hits in quick succession. Due to the low penetration, even reserve-level armoured vehicles might prove difficult targets. Anything with more than 20 mm of armour is better to avoid in combat. If you get close enough to a ground target, you might find this armament rather effective, but it is still strongly suggested to try to get your enemy from the side and rear where they are more vulnerable and pay less attention.

If you have enough elevation and a traverse speed to follow an air target, this gun can prove pretty effective against aircraft. A couple of hits and the target is likely to be either set afire or lose some critical components.

Pros and cons

Pros:

• Good fire-rate
• Effective against soft targets
• Effective against aircraft

Cons:

• Penetration a bit lacking
• Magazine has only 30 rounds

History

Developed by Hotchkiss & Cie in the mid 1920s, the Hotckiss Mle 1929 was a multi-purpose heavy machine gun. First used by the French Navy, it served as close anti-air defence for ships with a range of up to 2,500 metres. The Army also adopted the gun, but in the Mle 1930 variants. The difference was that the Mle 1930 wasn't equipped with the sight and mount that allow the machine gun to be used against aircraft, as the French Army worried that the bullets might fall back on civilian areas and potentially kill someone. The Army strictly used this armament as anti-tank and anti-infantry weapons in their service.

In the 1930s, the French cavalry mounted the 13.2 mm machine gun onto AMR.35 ZT1 reconnaissance vehicles to add some anti-tank capability to defend themselves during missions. This was also attempted on armoured cars such as the Laffly 80AM. Some machine guns were also presented for export, arming anti-aircraft trucks, though the export attempt as anti-aircraft had no success. As an independent heavy machine gun however, this armament was very successful, been exported notably to Brazil, Poland, and Romania, but also licensed to Italy and Japan, nearly all of which used the 13.2 mm intensively during WW2.
