Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Ammunition

The M1A1 HC is armed with the same 120 mm M256 smoothbore gun as the M1A1 and has access to the same ammunition of APFSDS and HEATFS. However, the M1A1 HC also gets access to a new HEATFS shell, M830A1. The M829 APFSDS round is still an excellent anti-tank munition, boasting the third highest penetration figures out of any sabot round in the game, at 493 mm of flat penetration at point-blank and decreasing to just 458 mm at 2 kilometres. Its angled performance is also excellent, penetrating 284 mm of armour at 60 degrees point-blank and 264 mm at 2 kilometres. It is sufficient to reliably engage any vehicle in the game frontally. The M830 HEATFS shell penetrates a meagre 480 mm of armour. It is not recommended to use this shell after unlocking the M829. The M1A2's new shell, M830A1 is a special type of HEATFS round. Instead of using a conventional impact fuse, M830A1 is a sub-calibre HEATFS round that has been saboted into a 120 mm casing and fitted with a proximity fuse. This allows it to effectively engage low flying aircraft and helicopters up to a range of 4.5 kilometres. The sub-calibre nature of the round means it travels extremely quickly at 1,400 m/s, making it the fastest HEAT round in the game. However, its effectiveness against armoured vehicles is limited as it penetrates a mere 350 mm of armour.

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

Pros:

• Same ammunition selection as the M1A2 at a slightly lower BR
• Has an active protection system that can provide protection against some ATGMs, also comes stock
• Better turret protection when compared to the M1A1
• M829 is a Tier I modification, with NVDs being Tier III
• Carries 4 charges of smoke grenades (4/16 compared to the 6/12 carried by its brothers)

Cons:

• No commander's sight
• APS is visible through night vision devices

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).
