Description
The TCM-20 was an Israeli modification of the M3 half-track with a TCM-20 turret. This was likely a field modification done by Israel during their early days with sparse military equipment, mounting TCM-20 turrets on decade-old vehicles, including captured 6x6 trucks, BTR-152, and M3 half-tracks. The TCM-20 turret itself was an upgraded M55 Quadmount turret (M45 turret on M20 trailer) with two Hispano Hs.404 20 mm autocannons for better firepower. The lack of documents on the introduction of these modified vehicles makes it hard to trace their history, but they were likely replaced by the more advanced M163 VADS (Hovet) with radar rangefinder by 1975.
Introduced in Update "Fire and Ice" along with the initial Israeli ground tree, players will soon find similarities with the M13 MGMC in service with the US Army. However, the .50 cal HMGs are replaced by two 20 mm HS.404 autocannons, enhancing its firepower against aircraft or sometimes suppressing ground targets if needed.
General info
Survivability and armour
The M3 half-track has been a staple of the US Army since the 1940s as one of the most widely-used half-tracks during the WWII alongside the Wehrmacht's Sd.Kfz series; these vehicles are a universal chassis which could be converted for different missions i.e. anti-aircraft. In Israel's case, the overall appearance of the TCM-20 is very similar to the M13 MGMC, but the larger guns and additional .30 cal M1919A4 gives its identity away. The vehicle is not rated for even rifle-calibre firearms at close distance. The thickest armour plate is the windshield, but do not expect it to stop HMG fire, even from afar. The engine block may absorb oncoming fire when head-on with enemies. In most cases, never, ever run into enemy fire lines or become targeted by aircraft, as these will end your career quickly; do also beware of high explosive shells or shrapnel, sometimes even close-calls could bring an end to the TCM-20.
Armour type:
- Rolled homogeneous armour
Armour | Front (Slope angle) | Sides | Rear | Roof |
---|---|---|---|---|
Hull | 6.35 mm (28-83°) 12.7 mm (1-27°) Driver windshield |
6.35 mm | 6.35 mm | N/A |
Turret | 6.35 mm (0-77°) Turret front | 6.35 mm | N/A | N/A |
Notes:
- Tracks are 15 mm thick
- Suspension wheels are 15 mm thick, with the bogie being 10 mm thick.
- Belly armour is 6.35 mm thick.
Mobility
M3 half-tracks share the same White 160AX petrol engine which could output up to 148 hp and the transmission could ensure its mobility both forwards and backwards; it can still retain the speed of all-wheel vehicles while crossing complicated terrain with ease.

Armaments
Main armament
The modified M55 turret (now called TCM-20) houses two HS.404 20 mm autocannon, the same gun used in many early French aircraft, with the same configuration and ammo count. Thanks to the flat ballistic of HS.404, players will soon get to grips with the performance of the cannons. Not only can it take out aircraft as it was intended, it also ensures that light vehicles will have to think twice before appearing in front of a TCM-20, the rate of fire and penetration will make sure they will not get away with ease.

To compensate for the lack of continuous firepower against infantry, TCM-20 installed a M1919A4 for the commander to suppress enemies; while it is ineffective against enemy armoured vehicles, there might be some occasions where enemies have exposed crews and the .30 cal could make short work of them.

Usage in battles
For players who have played the M13 MGMC in the US tech tree, it can be said that the TCM-20 is an successor to M13 to some extent, especially with its iconic twin gun configuration. However, when enemy aircraft get too close, they will find out the major difference: they would soon be shattered by the 20 mm HS.404 autocannons, recalling the memories from being chased by aircraft with these cannons. Such an "upgrade" is very welcomed as the 20 mm calibre is still more than enough to take out strafing fighters with ease, with overall 720 rounds onboard at 120 rounds per load, if players get used to the relatively straight ballistics and not being trigger-happy, the overall efficiency could be on-par with other SPAAs in other tech trees with their respective advantages. Most of all, the M3 chassis ensures that the TCM-20 can get to where it is needed as soon as possible thanks to its 72 km/h top speed, making it a viable option to flank enemies in some occasions; while the 13 km/h reverse speed could still make sure it can retreat to cover if masses of enemies/menacing aircraft rushing to where the vehicle is. As said, TCM-20 is still a half-track based SPAAG with minimal protection; in fact rifle-calibre firearms can harm the crew at around 200 m from the sides, let along HMGs and autocannons at even higher penetration, so be extra careful on where players should appear - rushing or running into a heated frontline is certainly a death sentence to the TCM-20. Overall, the TCM-20 is still a good AA half-track to handle different types of vehicles, whether it's on wheels, tracks or flying ones.
Pros and cons
Pros:
- Devastating 20 mm autocannon which works well against aircraft
- Rather mobile, can swiftly changes its position if needed
- Quick turret traverse speed for target acquisition
- Spare .30 cal machine gun for occasion unprotected crews of enemy vehicles
Cons:
- Lightly protected up to rifle calibre firearms, also prone to overpressure
- Relatively small ammo pool per load (60 per gun)
- Insufficient penetration due to the battle rating
History
Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main
template. Be sure to reference text and sources by using <ref></ref>
, as well as adding them at the end of the article with <references />
. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===
, also if applicable).
