FAI armoured car

The FAI was built on the chassis of the GAZ A car, a licensed copy of the American Ford A. This chassis was the major weakness of the FAI. Most commercial car chassis were not powerful enough to move a useful amount of armour or firepower on the battlefield. The Germans were known to get round this particular problem by designing a car chassis that was intended from the outset for both civilian and military vehicles and which was used successfully in at least one German armoured car family of this period. However, armoured cars based on commercial car chassis were, for the most part, road-bound, thinly armoured and lightly armed. The FAI was a typical example of this class of vehicle with a single 7.62 mm DT machine-gun in a revolving turret. The armour was sufficient to stop most shell fragments and small arms fire, but could not withstand any kind of cannon or heavy machine-gun fire. It was also very vulnerable to mines.

The FAI was built in relatively small numbers before being replaced by the very similar BA-20. The early BA-20 had the same vertically sided turret as the FAI. FAIs were employed in the early days of fighting on the Eastern Front in World War II.

The FAI and BA-20 series had a few advanced features. They were of all-welded construction in an era when very few AFVs were welded. Also, they had cork-filled tires to enable them to retain mobility even if the tires were penetrated.

The FAI and BA-20 are often mistaken for each other. The main recognition feature of the FAI is the two dome-shaped armoured covers over the driver and co-driver's stations. The BA-20 had a flat armoured roof in this area instead.
