As every want-to-be Car Warrior knows, the most
dangerous weapons any duelist can possibly come up against are tank guns
and artillery pieces. These one-way tickets to Highway One are capable
of destroying most civilian vehicles in one shot. Where these weapons fall
short is in being used against tanks themselves. As the rules for tank
combat are currently written, it takes numerous hits to breach the armor
of all but the most poorly-designed AFVs (to say nothing of destroying
the AFV itself). Even allowing for the improvements in AFV armor which
have taken place over the last half-century, this flies in the face of
even the most liberal interpretation of "game" reality. The following information
is presented in order to correct this situation. GMs are free to adapt
these statistics as they see fit.
Tanks first crawled across the battlefield during the latter stages of World War I. At first, they were armed with small-bore artillery artillery (37mm to 57mm) taken from naval vessels. As tank armor improved, specialized tank guns were developed. These weapons fired their projectiles at increasingly-higher velocities. Thicker armor was countered by increasing bore size. The tank gun of the 21st century is a marvel of military engineering, offering range, accuracy and firepower that would (in earlier times) be just short of miraculous.

Hypervelocity Gun Ammunition
There are several types of tank gun ammunition, each with different effects. This allows a gunner the flexibility of choice when engaging different kinds of targets.
HE (High Explosive) -- This shell consists of an explosive charge packed insidea metal casing. A HE shell allows a tank gun to function as an artillery piece. The cost, weight and damage of HE rounds are listed above.
APX (Armor-Piercing Explosive) -- An APX shell has a thicker casing made of stronger material. It also has a smaller explosive charge than an HE shell. This reduces the burst effect by 50%.
Beehive rounds have a special to-hit score of 2. This score is not affected by modifiers for speed, range, gunnery skill and targeting computers. Only those modifiers for target size and visibility apply. Beehive rounds are primarily used against enemy infantry and light (non-AFV) vehicles. However, they can also be employed against low-flying aircraft.
Artillery pieces are large-bore weapons with a
relatively-low muzzle velocity. They are divided into three types; howitzers,
field guns and mortars. Howitzers and field guns both have rifled bores.
However, a field gun has a longer barrel; this gives it a longer range.
A mortar is a smooth-bored weapon whose barrel is shorter than a howitzer
of equivalent caliber. Accordingly, the range is also shorter. A mortar
is incapable of using direct fire. However, it has the advantages of low
cost, light weight and small size (cost, weight and spaces are halved).
Mortar shells have thinner casings than artillery shells. Their powder
charges are also smaller. Therefore, mortars have twice the number of shots
per space for half of the WPS.

spaces, 50 DP; 50d damage, 20 crew, RoF 1/8, CPS 2,500, WPS 250. Burst
effect 8d damage in 10" radius.
Artillery Gun Ammunition: Warheads
Artillery pieces are bought unloaded. Separate storage space for the shells is required. Artillery ammunition takes up different amounts of space per shot. Accordingly, 50mm and 75mm shells take l/10 space per shot. 105mm shells take l/5 space per shot. Shells of 120mm to 200mm caliber take up one space each. The size of an artillery shell (in spaces) reflects both the actual projectile as well as its powder charge. Artillery pieces fitted with autoloaders must carry their ammunition in magazines ($50 and 15 lbs. per space of size).
HE (High Explosive) -- This has been the standard round for artillery pieces since World War I. It consists of a charge of explosive packed inside of a steel casing. Upon detonation, the case shatters into razor-sharp fragments.
APX (Armor-Piercing Explosive) -- This round is identical to the APX shell fired by tank guns. APX rounds were the standard ammunition for naval artillery for decades. APX artillery shells have l/2 the burst effect size of an HE shell of the same caliber.
Beehive -- Beehive shells fired from artillery pieces function the same way as Beehive shells fired from tank guns. The range of a Beehive shell of 120mm caliber and below is 100". For 150mm to 200mm caliber the range is 200". Mortars may not fire Beehive ammunition.
Scatterpack Oil -- CPS lx base, WPS normal. An oil shell covers an area equal to half its burst radius in a square -- a 150mm oil shell would generate a 2" x 2" oil slick. For 3.5x CPS, an oil shell may be loaded with flaming oil.
Scatterpack Paint -- CPS 0.5x base, WPS normal. Paint shells create a counter equal to the shell's burst radius in a square. For example, a 120mm shell would create a 3" x 3" paint counter.
Scatterpack Smoke -- CPS 0.5x base, WPS normal. Smoke shells create the same size counter as paint shells. The load can be changed to hot smoke for a 50% cost increase.
Scatterpack Tear Gas -- CPS: 2x base, WPS: normal.
As with smoke shells, tear gas shells create a counter the same size as
the one created by paint shells.
Artillery Ammunition: Guidance Systems
LG (Laser Guidance) -- All types of artillery shells may use laser guidance at the normal costs. The targeting laser doesn't have to be linked to the artillery piece. Laser-guided artillery shells have a to-hit value of 6. The beam of the targeting laser must remain locked on to the target for the last three turns of the shell's flight. If the target is closer than three turns, the beam must have a continuous lock on it.
TG (Teleguidance) -- CPS 5x base, to-hit 8. Teleguided shells have a miniature TV camera mounted in the nose, along with a number of small attitude-control rockets. This system allows a gunner or spotter to guide the shell to its target by remote control. No modifiers to the to-hit roll apply except for gunner skill and speed. The guidance control unit costs $2,500 and is 3 GE. The control signals can be jammed or bollixed. For 8x CPS, the control unit may use directional radio, making it immune to interference.
Seeking Projectile -- CPS 10x base, WPS normal, to-hit: 7. Seeking projectiles are essentially self-guided missiles that use either active radar homing or active laser homing (CPS 12x for a shell that can switch between the two). No targeting modifiers of any kind apply. This kind of shell may be modified for anti-radar homing at an extra cost of $1,000 each.
Remote Sensor -- CPS lx base (plus the cost of the sensors), WPS normal. This shell deploys remote sensors in the same way as a mine shell deploys mines. The sensors are inert until activated by remote command.
Rocket-Assisted -- CPS 2x base, WPS 2x base. Rocket-assisted
artillery shells ad 50% to the range of an artillery piece. This effect
is cumulative with the effect of a long barrel. Thus, a rocket-assisted
shell fired from a long-barreled artillery piece has 200% normal range.
There are a number of accessories which can greatly increase the usefulness of tank guns and artillery pieces. These are listed as follows.
Autoloader -- Artillery pieces fitted with autoloaders double their rate of fire (maximum RoF 1). Autoloading artillery of 50mm to 105mm bore has a crew requirement of 1 (the gunner). For artillery of 120mm to 200mm, the crew equirement is 2 (the gunner and an autoloader supervisor). The cost and weight of an autoloader is 50% of the basic artillery piece. The cost and weight of an autoloader is additional to the cost and weight of a long barrel. Thus, an artillery piece fitted with a long barrel and an autoloader costs and weighs 100% more than normal.
Long-Barrel -- For tank guns, this item gives the weapon a range modifier of -1 per 20", as long as the range is 20" or over. Targets within 20" take the full modifier. For artillery pieces, the addition of a long barrel multiplies the range of the weapon in question by 50%. Additionally, long-barreled artillery pieces have a range modifier of -1 per 20" when used in direct-fire operations (the same as for tank guns). Mortars may not be fitted with long barrels. A long barrel costs and weighs 50% of the weapon it is fitted to.
Mortar Modifications -- CPS: lx base, WPS: l/2 base. Mortar shells take up half the space of artillery shells. Thus, a 105mm mortar has 10 shots per space instead of 5.
