General info

While it is a cannon from 1914, it may seem weird that it comes with HESH. In reality, it's a flawed HEAT charge that has a poor fuse that would bend and mould the soft metal without fusing and directly detonate the explosive matter the moment it impacts the target, acting as HESH without the chemical effect.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The Cannone da 100/17 Mod.1914 is a howitzer and thus is difficult to learn to master. It provides the benefit of being able to knock out most vehicles at its rank. Care should be taken not to aim at gun barrels because these will reduce the lethality of the impact of the shell, unless the target is open-topped, in which case such an impact will not likely matter. Aim your shells at locations in which the enemy crew or shells will take the most damage, resulting in an instant knock-out.

In the tank destroyer role, the Cannone da 100/17 Mod.1914 will usually have a slow rate of fire, so care should be taken to max out the reloading and leadership skills, as well as ace status to ensure the reload time is as short as possible. The arcing trajectory means that it is uniquely suited to go after tanks in the hull down position, and can even be used to provide indirect fire for your team, though this will require extensive practice.

Pros and cons

Pros:

• Powerful shells that will critically damage or outright knock out tanks
• Arcing trajectory can be used to put down fire on tanks in hull down positions
• Access to HEAT and HESH shells at rank I

Cons:

• Long reload time
• Howitzer behaves differently than a cannon; more difficult to learn drop
• Large size makes it easy to damage

History

Examine the history of the creation and combat usage of the weapon 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-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 />.

Media

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