In general, the A.C.I is very good at head-on engagements, due to its very well armoured front for its BR. The sides are with a thickness of only around 45 mm relatively good penetrable at 2.7. Tanks using large-calibre HE shells are dangerous, because of the overpressure mechanics that will often take out the driver and the machine gunner as well as the transmission. The lower front is quite vulnerable, if shot, the transmission will most likely break down, the crew won't take damage usually.

Notes:

  • As they are modeled by sets of 2 or 3, shells disappear from the rack only after you've fired all shells in the set.
  • To go into battle with the turret empty of shells, pack 59 (+71) shells (racks 1 & 2 depleted).

Usage in battles

The A.C.I's sloped frontal armour is great in medium range skirmishes since it will bounce most shots. The weak gun however forces you to come close to your targets to get a chance to penetrate. The armour is best used in combination with the A.C.I's good mobility.

Notable enemies include the Panzer III, the Marder III H and the early T-34s.

Pros and cons

Pros:

  • Diversely sloped frontal hull armour is sturdy against common foes, like M3A3 Stuart and M5 Stuart, T-50
  • Outstanding gun depression, allowing hull-down tactics
  • Can easily frontally engage most enemies
  • Fast reload allows quick follow-up shots

Cons:

  • Only 44 mm of side armour
  • Painfully slow reverse speed of -4 km/h
  • Tightly packed crew
  • Frontal turret armour is quite weak
  • Slow acceleration

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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