General info
Survivability and armour
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 easy to penetrate at its BR. 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.

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
