Manual[ edit ] Most manual transmission two-wheelers use a sequential gearbox. Most modern motorcycles except scooters change gears of which they increasingly have five or six by foot lever. On a typical motorcycle either first or second gear can be directly selected from neutral, but higher gears may only be accessed in order — it is not possible to shift from second gear to fourth gear without shifting through third gear. Neutral is to be found "half a click" away from first and second gears, so shifting directly between the two gears can be made in a single movement.

The M 25mm "Bushmaster" Chain Gun, manufactured by McDonnell Douglas, has a single barrel with an integrated dual-feed mechanism and remote ammunition selection.

Either armor piercing AP or high explosive HE ammunition may be selected with the flick of a switch. The Gunner may select from single or multiple shot modes. The standard rate of fire is rounds per minute, and has a range of 2, meters depending on the ammunition used.

A wide range of ammunition has been developed for this weapon, making it capable of defeating the majority of armored vehicles it is likely to encounter, up to and including some main battle tanks.

The M mm, fully automatic, externally powered gun can destroy lightly armored vehicles and aerial targets such as helicopters and slow-flying aircraft. It can also suppress enemy positions such as troops in the open, dug-in positions, and built-up areas. The primary role of the BFVs during combat in urban areas is to provide suppressive fire and to breach exterior walls and fortifications.

The wall and fortification breaching effects of the mm automatic gun are major assets to infantrymen fighting in urban areas. The mm gun produces its best urban target results when fired perpendicular to the hard surface zero obliquity.

During urban combat, however, finding a covered firing position that permits low obliquity firing is unlikely, unless the streets and gaps between Automatic sprocket are wide. Most shots impact the target at an angle, which normally reduces penetration. The rounds tend to dislodge more wall material for each shot but do not penetrate as deeply into the structure.

Reinforced concrete walls, which are 12 to 20 inches thick, present problems for the mm gun when trying to create breach holes. It is relatively easy to penetrate, fracture, and clear away the concrete, but the reinforcing rods remain in place.

These create a "jail window" effect by preventing entry but allowing grenades or rifle fire to be placed behind the wall. They can be cut with demolition charges, cutting torches, or special power saws. The mm gun more easily defeats brick walls, regardless of their thickness, and the rounds produce the most spall.

The mm gun is devastating when fired against sandbag bunker walls. Obliquity has the least affect on the penetration of bunker walls. Bunkers with earth walls up to 36 inches thick are easily penetrated.

At short ranges typical of combat in urban areas, defeating a bunker should be easy, especially if the mm gun can fire at an aperture.

Although the penetration achieved by the two combat rounds-armor-piercing, discarding sabot with tracer APDS-T and high explosive, incendiary with tracer HEI-T -differ slightly, both are eventually effective. However, the best target results are not achieved with either of the combat rounds.

At close range against structural targets, the training round TP-T is significantly more effective. The TP-T round, however, has little utility when used against enemy armored vehicles.

The APDS-T round penetrates urban targets by retaining its kinetic energy and blasting a small hole deep into the target. The APDS-T round gives the best effects behind the wall, and the armor-piercing core often breaks into two or three fragments, which can create multiple enemy casualties.

When firing single rounds, the APDS-T round provides the greatest capability for behind-the-wall incapacitation. The APDS-T round can penetrate over 16 inches of reinforced concrete with enough energy left to cause enemy casualties.

It penetrates through both sides of a wood frame or brick veneer building. The APDS-T round creates a hazardous situation for exposed personnel because of the pieces of sabot that are thrown off the round. The danger zone extends at an angle of about 10 degrees below the muzzle level, out to at least meters and about 17 degrees left and right of the muzzle.

The HEI-T does more damage to an urban target when fired in multiple short bursts because the accumulative impact of multiple rounds is greater than the sum of individual rounds.

A dual-feed system uses sprockets and extractor grooves to control rounds. A system of clutches allows either sprocket to engage and feed either an AP or HE cartridge. One Bradley ammunition box holds 70 rounds, and the other holds rounds. Each box can hold either AP- or HE-type ammunition.

The enhanced gun uses a 1. For all mm guns, unit maintenance replaces inoperable 1. The gun also has quick-detachable link covers, a larger breach assembly, longer recoil, and a triple-spring drive clutch.

It also has a built-in test BIT for the feed-select solenoid and gun-drive motor. The feed-select solenoid and the gun-drive motor each contains a jumper wire that enables the on-vehicle BIT.

The gunner can choose from three rates of fire: Single Shot - the commander or gunner can shoot about as fast as he can squeeze the trigger.Sheldon says: Chain maintenance is one of the most controversial aspects of bicycle mechanics.
