|— In-game description|
The O'Brien V.121 Highlander seats a crew of 2 (1 driver, 1 gunner), both safely enclosed in the vehicle.
The single inventory slot is reserved for the 7.92mm magazines (can stack up to 100 magazines).
It's armed with the same twin barreled 7.92mm machine guns as the O'Brien V.110. It has a 50 round magazine, a moderate reload time, and a 5 rounds/s fire rate. Despite the machine gun’s capability of 360 degree rotation, the rotation speed is relatively slow. The gun has good accuracy but significant and must rely on short bursts to hit far targets.
Health & Armor
Even though tracks often suggest hard armor, the Highlander has the same light armor as the standard AC. It's able to soak small arms fire and shrapnel but anything else should be considered a dangerous threat. It won't last long when faced with heavy calibers, heavy explosives. Anti-tank weaponry is almost always a death sentence.
The vehicle's treads do not count as actual tracks that can be disabled, unlike every other tracked combat Vehicles.
Engine & Size
The treads offer increased off-road mobility over the standard O'Brien V.110, especially on snowy and mountainous terrain. However it's slightly slower on roads. Its treads also allows it to turn faster. Its engine has an okay fuel consumption rate which reduces the vehicle's autonomy. Any long term use will require a reliable source to refuel.
The Highlander movement isn't affected by Snow Storms.
It is heavy enough to trigger anti-tank mines but still light enough to safely cross Field Bridges without damaging them too much. It is too small to cross Trenches. It can run over Sandbags and tier 1 walls but can't run over Barbed Wire Fences.
The Highlander fares better off-road than other Armored Cars but is still very vulnerable to Anti-Tank Mines, a single one nearly kills it. Like the other offensive vehicles, it's strongly advised for the crew to wear gas masks and filters once Green Ash is unlocked. It's also better to not use the car at night due to the limited visibility.
Because it is chambered in a smaller caliber, the Highlander cannot damage defenses and struggles to suppress them due to its bad accuracy. As such it shouldn't be used to push lines of defenses with active AI. It is much better suited to attack enemy infantry out in the open or behind passive defenses (Trenches, Sandbags, etc...). It works well as an infantry support role, the friendly infantry protects the vehicle's flanks and spots AT mines for it while it suppresses and kills the enemy infantry in defensive positions.
When attacking a defensive position it's advised to use the Highlander backwards (rear to the enemy and turret facing back) to allow a quicker retreat, because the vehicle is faster when moving forward and its armor identical on all sides.
Once heavy anti-tank weapons are unlocked the O'Brien becomes pretty much obsolete on the front line, because they kill it very quickly, and the vehicle lacks a spotter position to warn the crew in advance.
The standard ACs equipped with machine guns are excellent against small groups of enemies attacking your back lines on foot or with a LUV since they rarely have the heavy weapons, the numbers, or the defensive positions to kill an Armored Car, especially early in the war. However it's not advised to fight a Landing APC if one attacks your back lines due to the high chance of it carrying heavy weaponry.
During Snow Storms
The Highlander's movement isn't affected by Snow Storms. It is the ideal MG mounted vehicle during snow storms because the Half-Tracks, Landing APCs, Field Guns and the open top Armored Car variants absolutely require the crew to wear snow uniforms and make stops to warm up otherwise their gunner would risk freezing to death and they are slowed by the snow when off-road. This leaves the Highlander and other closed-top Armored Cars as the only usable combat vehicles during snow storms before tanks are unlocked.
