The Armored Car retains classic fast unit strengths, being very effective against ranged units, but it’s weaknesses are now theoretically heavy units and artillery units and is on even terms with light units instead. They have moderately high attack and defense, making them extremely useful with high army boosts.
On the new Progressive Era battlefield, it gains defense bonus when position on plains, and can move through barbed wire easier, but cannot travel through trenches and rocks which may limit their movement. Their mobility and range can sometimes allow them to hit across the map even on the first turn.
The Armored Car is mostly effective in easy terrain due to their extremely high movement combined with a decent range of 9 (6 tiles on the Progressive Era map). Their only real problem is the Tank as they have massive bonuses against them.
Against Same Age Units
Neither side has bonuses against each other but usually the Armored Car has a better advantage of slightly higher attack, defense and movement. If the Conscripts are in trenches, then they will prove rather difficult to kill however.
The Armored Car is extremely strong against the Sniper. With an additional bonus of 25 attack and defense, Armored Cars can easily finish Snipers and take very little damage in return. However they may be difficult to kill in Forests and at a distance but usually the Armored Car’s fast movement is good enough.
The Armored Car is extremely weak against the Tank, due to their bonuses of 50 attack and defense. They take little damage from Armored Cars and do massive damage to them, so Armored Cars should be supported by other units when facing Tanks.
The Armored Car is theoretically weak against the Rapid Fire Cannon, however, given the rather low attack and defense of the Rapid Fire Cannon despite a bonus of 25, they are not too big of a threat in most situations especially as Armored Cars have high mobility and range. However Rapid Fire Cannons may be difficult to kill if there is a lot of rough terrain between them.
The first effective use of an armored vehicle in combat was achieved by the Belgian Army in August–September 1914. They had placed Cockerill armour plating and a Hotchkiss machine gun on Minerva touring cars, creating the Minerva Armored Car. The unit is also the very first fast unit to not be mounted.
