General info
Survivability and armour
The M18 GMC (China) has extremely thin armour throughout its construction. As such, a player with the M18 should throw away any notion of trying to survive a shot and instead aim to avoid being hit at all. With an open-top construction and the placement of certain crew members, even enemy machine gun rounds can knock out the crew members inside and lower combat efficiency.
The thin armour is also both a blessing and a curse for the vehicle. It is a curse as it means the vehicle can suffer through the hull-break mechanics. A single shell has the potential of knocking out the M18 instantly regardless of how many crew member it defeats. The blessing is that if the enemy kinetic round hits the M18 and does not meet the requirements for a hull-break, the M18 may end up with minimum critical damage such as a damaged module or crew member. As such, there can be second chances for this vehicle, but as mentioned, this should not be relied upon as a combat strategy.
With five crew members, the M18 has a standard amount of crew to survive off of. Three are essential for combat efficiency: the gunner, loader, and driver. The commander operates the cupola machine gun and if knocked out will cause the machine gun to no longer function. This will be a constant occurrence due to the position of the commander model with the torso exposed above the turret, and so enemy machine gun rounds can hit and incapacitate the commander from the vehicle's functions.
The M18's module configuration is rather standard with the transmission in front and engine in the back. The spread out nature means there are more "wiggle room" for kinetic shells to hit and pass through around the modules, but it also means that any part of the M18 exposed can be hit and induce a hull-break.
Mobility
Though the previous section on armour may imply poor survivability, the M18's shining trait will be in its mobility. It produces enough engine horsepower to become a speed demon on the battlefield, quickly traversing through rough terrain to get to advantageous positions to ambush enemies that are just starting to get to the fight.
The vehicle displays great mobility when driving forwards and backwards, and so it can perform quick exits from a compromised position.

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).
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

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.
