Confederation Authorized Volunteer Armed Long Range Yeomanry: Organization
I don't think that anything that flies is going to have a long life span, unless it's very fast and/or has super heavy armour and protection.
And that seems more Confederation Army, and Confederation Marines in assault shuttles.
Ideally, at the ground level, you want a tracked Merkava type armoured/infantry fighting vehicle, with the engine in front, and a cargo space in the back that can be configured to embark fully equipped troops, or act as a command post; primary hatch is in the back.
Organization would be as a squad, patrol in our case: the vehicle crew is a three man lance with commander, gunner and driver; two rifle and/or specialist lances of about six men, and the squad leader. You want to limit this to about seventy tonnes.
The Confederation would want to standardize this in Home Guards, so that if Confederation military ground forces turn up, they can immediately requisition them.
The cargo space can also be used to carry extra ammunition, or act as an ambulance.
Normally, I tend to think that a four man heavy tank tends to be a valuable asset that all efforts would be made to protect it, or in the event of being incapacitated, recovered.
Whereas a three man tank is considered disposable, made as light and as small as viable, and abandoned the moment it can't move and/or fire.
A. A carbine barrel would reduce range to two hundred twenty five and one hundred thirty five metres, minuses off a point of damage, is twenty percent lighter than the default rifle barrel, and is a sixth cheaper.
B. An assault barrel drops a complete dice, which would make the light ne dice, and the intermediate two dice; range would be reduced to seventy five and one hundred twenty five metres; the cost would be a third cheaper, while the weight is forty percent less than the default rifle barrel.
C. The handgun barrel drops both a dice in damage and minuses off one point of penetration; range is thirty metres and fifty metres; cost is half a default rifle barrel, while the weight is forty percent thereof.
The .22 LR is effective to 150 yd (140 m), though practical ranges tend to be less. After 150 yd, the ballistics of the round are such that it will be difficult to compensate for the large "drop". The relatively short effective range, low report, and light recoil have made it a favorite for use as a target-practice cartridge. The accuracy of the cartridge is good, but not exceptional; various cartridges are capable of the same or better accuracy. A contributing factor in rifles is the transition of even a high-velocity cartridge projectile from supersonic to subsonic within 100 yd (91 m). As the bullet slows, the shock wave caused by supersonic travel overtakes the bullet and can disrupt its flight path, causing minor but measurable inaccuracies.
When zeroed for 100 yards (91 m), the arc-trajectory of the standard high-velocity .22 LR with a 40 gr (2.6 g) bullet has a 2.7-inch (69 mm) rise at 50 yards (46 m), and a 10.8-inch (27 cm) drop at 150 yards (140 m). A .22 LR rifle needs to be zeroed for 75 yards (69 m) to avoid overshooting small animals like squirrels at intermediate distances.
As a hunting cartridge, rimfires are mainly used to kill small game up to the size of coyotes. Although proper shot placement can kill larger animals such as deer or hog, it is not recommended because its low power may not guarantee a humane kill. In 2013, an elephant was killed by multiple shots from a .22 LR rifle.
Because a .22 LR bullet is less powerful than larger cartridges, its danger to humans is often underestimated. In fact, a .22 LR bullet is easily capable of killing or injuring humans. Even after flying 400 yards (370 m), a .22 bullet is still traveling at about 500 ft/s (150 m/s). Ricochets are more common in .22 LR projectiles than for more powerful cartridges as the combination of unjacketed lead and moderate velocities allows the projectile to deflect – not penetrate or disintegrate – when hitting hard objects at a glancing angle. A .22 LR bullet can ricochet off the surface of water at a low angle of aim. Severe injury may result to a person or object in the line of fire on the opposite shore, several hundred yards away. A .22 LR bullet is capable of traveling 2,000 yards (1,800 m), which is more than 1 mile (1.6 km).
