Survivability and armour

Being a light tank the Stuart I has fairly thin armour, it can generally protect against most machine guns but will usually not stand up against the main weapons of most enemy tanks at its BR. The inside of the tank is fairly cramped with the two turret members standing, this means that the likelihood of a crew member being hit is fairly high.

Armour type:

• Rolled homogeneous armour
• Cast homogeneous armour (lower frontal plate)

Armour	Front	Sides	Rear	Roof
Hull	38.1 mm (18°) Driver Port 15.8 mm (69°) Front Glacis	25.4 mm	25.4 mm	12.7 mm
Turret	38.1 mm	25.4 mm	25.4 mm	12.7 mm

Notes:

• Suspension wheels and bogies are 15 mm thick, tracks are 10 mm thick.

Mobility

Game Mode	Max Speed (km/h)		Weight (tons)	Engine power (horsepower)		Power-to-weight ratio (hp/ton)
	Forward	Reverse		Stock	Upgraded	Stock	Upgraded
Arcade	56	7	12.7	406	500	31.97	39.37
Realistic	51	6		232	262	18.27	20.63

The Stuart I can reach a speed of 49 km/h off road and up to 50 km/h on road. It can feel sluggish while turning at lower speed as it lacks neutral steer, but when moving forward the turning is much smoother and quicker. The vehicle reverses at up to 5 km/h which while somewhat slow, is still usable in most situations on the battlefield.

Armaments

Main armament

The main gun of the Stuart I is a 37 mm M5 cannon, this gun is also featured on the M2A4 and M3 Lee, On the Stuart I the M5 can use 2 round types, either M74 (AP) or M51 (APCBC) with the latter being a Tier 1 modification.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
