JR7-D Jenner

Introducedjenner.png in 2784, the fact that the Jenner was the sole property of the Draconis Combine was long a source of national pride. Designed, produced and (for over fifty years) solely used by the Combine, the Jenner was meant to be a fast guerrilla fighter which would go on to form the foundation for highly mobile lances. Five Smithson Lifter jump jets, two in each side torso and one in the center torso, gave it a jumping distance of 150 meters, while its 245-rated Magna fusion engine allowed for a top speed of over 118 km/h, making it faster than most other ‘Mechs. The drawback of the original model was its armament of a Diplan HD large laser and two Argra 27C medium lasers, all mounted in a turret which could be easily disabled with a well-placed shot, while the medium lasers’ targeting systems proved to be bug-ridden. After some tinkering this setup was eventually replaced with the weaponry found in the JR7-D model, creating a good mix of speed and firepower, though only four tons of armor provide paltry protection compared to other ’Mechs in the same weight range.

The Jenner became the standard light warhorse of the DCMS with the outbreak of the First Succession War, though its reputation would be forever tarnished following its role in the Kentares Massacre. Construction of new Jenners continued at Diplan MechYard’s factory on Ozawa until a raw mineral shortage caused a halt in 2815, though they continued to produce new chassis. In 2823 production resumed on Ozawa, with some three thousand chassis shipped to Diplan’s subsidiary on Luthien for final assembly, which itself was retooling to being full-scale production; by 2830 both production lines were producing 1,350 Jenners a year. The sheer destruction of the Succession Wars finally took their toll when the last Jenner factory was destroyed in 2848, though so many Jenners had been produced by then that nearly every DCMS battalion had at least one of these ’Mechs well into the War of 3039. While the other Successor States eventually managed to procure operational Jenners (every AFFS regiment along the Combine border had at least one), the design remained in predominant use by House Kurita.

A favorite tactic of Jenner lances was to gang up on larger ‘Mechs and unleash a devastating alpha strike. One or two of the ’Mechs would be equipped with inferno rounds, so even if the enemy survived the first strike they were badly damaged and running hot, allowing the Jenners to jump to safety and cool down themselves. A few seconds later the attack would be repeated until finally the enemy was dead. It was also common practice to pair the Jenner with another Combine ’Mech, the Panther, creating a deadly combination of sheer speed and firepower with the slower Panther provided cover fire for the Jenner’s flanking attack. The Jenner was such a favorite among Kurita MechWarriors that it became the benchmark against which all other newly designed Combine ’Mechs were compared.

Weapons and Equipment

The primary weapons system on the Jenner is four Argra 3L Medium Lasers, two each mounted in directionally variable mountings on either side. These provide the Jenner with a powerful close-to-medium range striking capability that does not suffer from a lack of supplies when operating behind enemy lines, though the use of only ten heat sinks means it has the potential to run hot. The lasers are backed up by a Thunderstroke SRM-4 launcher in the center torso, supplied by a ton of ammo in the right torso, that can be used after breaching an enemy’s armor to try and get a critical strike against vulnerable exposed internal components.
