Like many of the Clan warriors it represents, the predator for whom Clan Smoke Jaguar is named owes its existence to science tampering with nature. Its genes are those of the Terran jaguar, altered in the laboratory to enable it to survive in a harsher environment. Imported by Aleksandr Kerensky's followers to the world of Strana Mechty, the smoke jaguar thrived in the fertile jungles that teemed with suitable prey.

Members of Clan Smoke Jaguar take fierce pride in their namesake, which the Clans' revered founder, Nicholas Kerensky, chose for them. They believe that Nicholas modeled all of Clan society on the smoke jaguar, and point proudly to the above entry from one of his many journals in which he extols the beast's virtues. Modern-day Smoke Jaguars often quote from this journal entry, which they revere above all literature save for the Clans' epic poem, The Remembrance.

The bidding for the Battle of Tukayyid began on the 18th of April, with all the invading Clans vying for the landing order and target cities they considered would win them the greatest glory. Led by Clan Smoke Jaguar, the Khans of the other invading Clans concentrated on preventing Clan Wolf from winning favorable battle conditions. The conspiracy apparently succeeded; Clan Wolf ended up landing five full days after the other Clans, and won the right to attack the smallest and least well-defended cities of Brzo and Skupo.

Khan Osis of Clan Smoke Jaguar rejoiced in having beaten the Wolves, and also in having won the honor to be the first to set foot on Tukayyid. He believed that ComStar's ComGuards would be easy pickings because ComStar had only shown the Clans its pacifist side. That Jaguars' target cities also promised the Clan great glory in the winning of them, as both lay in terrain heavily favoring the defender; Dinju Heights nestled in the Dinju Mountains, and Port Racice lay near the treacherous Racice River Delta. Refusing to listen to the ilKhan's warnings about the dangers of scarce supplies, the Jaguar Khans landed woefully unprepared for the battlefield siege they were soon to face. Instead, the Jaguar Khans placed their faith in the ability of their Galaxies to overwhelm all opposition with two swift, brutal strikes.

Khan Osis led Alpha Galaxy, including the elite Sixth Jaguar Dragoons and the Jaguar Grenadiers, into the Dinju Mountains. Meanwhile, saKhan Weaver and the Mistweavers Galaxy landed in the marshes of the Racice River Delta. Both Khans expected easy victory; neither was to have it.

The Dinju campaign began well for the Clan; the Sixth Jaguar Dragoons cut through the ComGuards' green Fiftieth Division and easily secured Alpha Galaxy's drop site. When the Dragoons and the Jaguar Grenadiers began their march on Dinju Heights, they encountered only modest resistance from remnants of the Fiftieth, whose light raids did little damage. The Clan warriors advanced toward the seemingly undefended Dinju Pass, confident of swiftly capturing the city that lay beyond. Unknown to the Jaguars, they were marching straight toward the heavier elements of the ComGuards' 299th Division, hidden in the pass.

Only the un-Clanlike caution of Star Colonel Brandon Howell saved the Jaguar Grenadiers from annihilation. Believing the undefended pass too good to be true, Howell sent two Stars of the Grenadiers forward in a ploy to force any hidden ComGuards out into the open. He then ordered the rest of his OmniMechs to hug the walls of the pass while moving forward at flank speed. Though the Grenadiers took heavy losses when the 299th sprung the trap, elements of the unit broke through ComGuard forces to confront the 323rd Division on the doorstep of Dinju Heights.

Not to be outdone by one of his own Star Colonels, Khan Osis attempted to lead his Sixth Jaguar Dragoons on a similar charge through the pass. Unfortunately for the Dragoons, the remaining 'Mechs of the 299th and 323rd Divisions were swarming all over the floor and the far end of the pass. The Dragoons took heavy casualties, and a ComGuard MechWarrior picked off Khan Osis with a well-placed laser shot against Osis's Summoner.

In the meantime, saKhan Weaver and the Mistweavers' OmniMechs bogged down close to their landing zone. The initial drop went well; the pools and marshes of the Racice Delta gave the Smoke Jaguar 'Mechs and Elementals a soft landing, inflicting fewer casualties than usual for such a maneuver. The Jaguars discovered, however, that wading through the swamps forced them to move at a painfully slow pace. ComGuard 'Mechs concealed in the delta's deep pools and sluggish river channels repeatedly ambushed the Jaguars, negating the Clans' weapon-range advantage and their 'Mechs' superior heat-sink technology. Ongoing artillery barrages herded the Clan 'Mechs ever deeper into the delta, where still more ComGuard 'Mechs waited in ambush. Near the end of the third day's march toward Port Racice, the 'Mechs of the ComGuards' 207th Division surrounded the Galaxy's Command Star and launched a coordinated attack against its units. Khan Sarah Weaver died in the fighting when her Warhawk's fusion engine went critical.

With the leaderless Clan Smoke Jaguars facing the fresh troops of the ComGuards' Second Army, ilKhan Ulric Kerensky ordered the Jaguars to retreat from Tukayyid. The dispirited warriors of the Mistweavers Galaxy obediently retreated towards their drop zone, but several of Alpha Galaxy's units refused. The Sixth Jaguar Dragoons viewed ilKhan Kerensky's orders as a Wolf Clan snub intended to erase the honor they had gained through the sacrifice of the Jaguar Grenadiers and the loss of Khan Osis. Proud and defiant, they continued their advance down the Dinju Pass, accompanied by several warriors from Alpha Galaxy's surviving Clusters. The sheer numerical superiority of the ComGuards' forces in the pass, however, eventually overwhelmed them.

Unable to fight their way back through the pass to aid their floundering companions, the few remaining warriors of the Jaguar Grenadiers launched a death-or-glory attack on Dinju Heights. The assault had no chance of succeeding, but forced the ComGuards' Eighty-second and 322nd Divisions to pull back into the city. With the ComGuards' retreat, a few of the Grenadiers managed to escape back to their drop zone.

The Smoke Jaguars suffered considerable losses of manpower and equipment to ComStar forces on Tukayyid, but unlike the other Clans, have not managed to recover sufficiently to resume military operations in the Inner Sphere to any significant degree, being kept in a defensive stance by several sources.

Kurita raiders have staged near-constant raids against Clan Smoke Jaguar in recent years, which have prevented that Clan from effectively recovering from the heavy casualties it suffered on Tukayyid. Nova Cat raiders have begun harassing Smoke Jaguar forces recently as well, further hampering the Clan's attempts to rebuild. As a result, the Smoke Jaguars seem unlikely to challenge the Ghost Bears for leadership of the Clans. Clan Smoke Jaguar's weakness has filled its warriors with frustration and a fierce desire to prove they are still a force to be reckoned with - which makes the Jaguars a potentially dangerous enemy for their Clan brethren and Inner Sphere powers.

Neither the Steel Vipers nor the Nova Cats have the strength to challenge the Ghost Bears, but both Clans are far from harmless. The Viper Khan, Perigard Zalman, has shown remarkable restraint while patiently rebuilding his Clan, which marks him as a canny and dangerous leader. Meanwhile, the Nova Cats continue to rebuild following their losses on Luthien and Tukayyid. Their weakened condition, however, has not prevented them from raiding worlds located above the truce line.

In an attempt to weaken both the Ghost Bears and Smoke Jaguars to give themselves time to recover from the refusal war with Clan Jade Falcon, the then-Jade Wolves set into motion a complex plan, with layers of plots and misinformation blaming both Clan Smoke Jaguar and the forces of Phelan Kell's Clan Wolf in Exile for the theft of genetic material of the Clan Ghost Bear founders. The Ghost Bears, through a series of raids and information gathering missions, discovered the true nature of this deceit.

Although discovering that the blame lie with the Jade Wolves and not Clan Smoke Jaguar, the relative weakness of Clan Smoke Jaguar has left that Clan open to raiding and perhaps a trial of absorption by Clan Ghost Bear. Whether the Ghost Bears take advantage of this opportunity or not is left to be seen.
