Recognizing that the Rifleman was a good design that could be improved, the designers at Kallon Industries began reviewing the RFL-3N's original design in light of its battlefield performance. Three facts immediately came to light. The Rifleman was prone to overheating, it did not carry enough ammunition, and it was lightly armored in comparison with other 'Mechs of the same tonnage. Kallon designers reworked the blueprints, making a few trade-offs, and created a first-grade 'Mech -- the JagerMech. Though still lightly armored for its weight, the JagerMech is less likely than the Rifleman to overheat, as the large lasers have been replaced with more ammunition and a pair of Mydron light autocannon.

         Four autocannon make the JagerMech an excellent fire support unit. Having approximately 20 rounds per cannon allows it to maintain bombardment for a long period of time. The JM6's autocannon can prepare the way for a storm assault or a siege because of their long-range accuracy.
         The JagerMech is also well suited as an anti-aircraft gunner. It boasts impressive accuracy due to its Garret D2j targeting and tracking system and the extended range of its Mydron Model D autocannon. These systems are usually used in tandem with the less accurate but more powerful Model C autocannon to give a better potential damage rating. The result is an anti-aircraft platform with impressive firepower.
         JagerMechs have led raids on several occasions. These raids have been rather successful as the JM6's long-range firepower can soften up the opposition before the lighter 'Mechs move in to attack at close range. The JagerMech itself will rarely close in, preferring to stay at long range to aim its autocannon accurately. As a last resort, however, the JM6 will close with enemy units, relying on its own weight and its Magna medium lasers. Although the 'Mech lacks arms for punching, its kick can inflict serious damage, and its charging attack can do more. Even though its medium lasers are not heavy short-range weapons, they can still out-gun most light 'Mechs.

         Today, most of the operational JagerMechs are in the service of House Davion and Liao. Marik and Steiner have only a few JM6s.
         Hanse Davion is particularly fond of the design, feeling that it is a good complement for the older Rifleman. For this reason, he has made a special effort to gather as many JM6s as possible for his 'Mech regiments, mixing JagerMechs and Riflemen freely in his fire lances.
         This mix proved to be successful during a raid on Demeter in April 2993. Davion forces on the planet were cut off from their supply base for two weeks. It was only the large supply of autocannon ammunition carried by the JagerMechs that kept the Riflemen in the fight. By sharing ammunition, the Davion force was able to continue fighting effectively until they could break through to their depot.
         However, the JagerMech has also had its share of disasters. In the so-called War of Teng, fought between February and March of 2890, Garth's company of the Capellan Hussars trapped a group of privateers in the Gartol Hills north of the capital city. Expecting an easy victory, Garth stationed his entire lance of JM6s at the foot of a narrow valley, with orders to begin firing as soon as the enemy was in range. The theory was simple: drive the privateers into the valley and trap them under the JM6's autocannon. Unfortunately, five of the raiders escaped the trap and rushed the JagerMechs' position. Lacking sufficient short-range armament to defend themselves, three of the JagerMechs were badly mauled, and the pirates escaped. Although the renegades were later hunted down, the Hussars were stung by the experience and have since been reluctant to use the JM6 extensively.
         Most 'Mech forces have little reservation about using JagerMechs, however. It is highly regarded for its long-range guns and its excellent tracking. In combat, it is usually deployed behind the lines or assigned companions with short-range weaponry.

         The JM6-A is the only notable variant of the JagerMech, mounting two Zeus LRM-15s in place of the medium autocannon. This version was designed expressly for anti-aircraft work and was produced in limited numbers. Most existing JM6-As are in service to House Davion.

Lieutenant Timothy Ingram
         Ingram has commanded his fire lance in Smithson's Chinese Bandits for eleven years. He is a proud man, dedicated to his craft and to his regiment. His grey and black JagerMech has a damaged hip actuator, giving the 'Mech a distinctive limp. Ingram is reputed to be a first-rate strategist who knows just where to concentrate his fire for the best effect. Although he has been offered lucrative commissions in the regular forces of House Davion and House Liao, Ingram remains loyal to the Bandits.

MechWarrior Donald Vincent
         Vincent is a roving adventurer. When the Crimson Ace Dragoons, a small mercenary force, was destroyed on Tiber in an assault against House Marik, he managed to escape with his 'Mech intact. Since then, he has served a variety of petty lords and landholders, but his moody nature and violent temper have often cut his employment short. He is most famous for walking his 'Mech through the palace of a former employer after a wage dispute.

MechWarrior Diana Cheung
         Cheung was given her JagerMech after long years of service as a Tech with the Davion Guards. Although some MechWarriors looked down on her, she has proved herself repeatedly in battle and is gaining grudging respect from her peers. Cheung's JagerMech is old and battered, but she has the technical knowledge necessary to keep it battle-ready. Through her constant care, the 'Mech is coming into mint condition.
