Commander of the Sixth Division
Promoted to the rank of Precentor in 3045, Yekel was assigned command of the green-ranked Sixth Division sometime prior to 3049. Immediately prior to the Clan Invasion, the headquarters of Yekel and his Alert Words was Kearny in the Free Worlds League.
Assigned along with the rest of the Sixth Army to face Clan Steel Viper during the Battle of Tukayyid, the Sixth Division was positioned just outside the hellish Devil's Bath, a horrific combination of geysers, boiling mud and narrow paths walled by massive granite columns, stretching for dozens of kilometers between the Vipers' intended dropzone and their target cities. After an initial exchange of fire, the Sixth withdrew into the Bath, luring the Steel Vipers in.
With the tight paths negating the Clan weapons' superior range and missteps sending entire Stars into the bottomless pools of boiling mud, Khan Natalie Breen realized too late her troops had stumbled into a massive trap. As the Vipers attempted to withdraw, a desperate Yekel used his Atlas's Satellite Uplink to personally issue a insulting public challenge throughout the Tukayyid system to goad Breen into continuing the attack. Now enraged by the insult, the traditional minded Vipers redoubled their advance, pushing the Sixth and Seventh-Eighth Divisions through the Bath. While inflicting extremely heavy damage on the Com Guard forces, both of the Vipers' Alpha and Gamma Galaxies used up their ammunition at a tremendous rate.
With any hope of resupply dashed when the Com Guards' elite First Division struck the Vipers' supply lines, saKhan Perigard Zalman ordered Gamma Galaxy's 57th Striker Cluster to divide the Com Guard units and pin down the Sixth. While the Fifty-Seventh was utterly destroyed as a viable combat unit as the 78th Division desperately tried to link up with the Sixth, it allowed Alpha Galaxy to completely surround Yekel's division. Recognizing his unit was doomed, Yekel attempted to offer himself in return for the surrender and survival of his troops, but discovered the price of insulting the Vipers. Specifically because Yekel asked for mercy, Khan Breen ordered her warriors to refuse all attempts at surrender and pledged to hunt down any of his MechWarriors who escaped from either the Devil's Bath or Tukayyid. 
The enraged pilots of Alpha's assault OmniMechs fell upon the Sixth, obliterating it down to the last 'Mech as their Khan commanded. But it was thanks to sacrifice of the Sixth and its fellow Seventy-Eighth Division that the Steel Vipers were ultimately driven from Tukayyid in defeat, the Vipers' frontline Galaxies having expended all their strength to destroy them. 
Despite Breen's threat, Yekel was among the members of the Sixth Division to survive Tukayyid. For his performance in the Devil's Bath, Yekel was promoted to command of the Eighth Army, posted along the border of the Lyran Alliance and Free Worlds League. After the retirement of Precentor Martial Anastasius Focht in 3061, Yekel was open in his opinion that Victor Steiner-Davion's appointment as Focht's successor only increased the public relation problems for both ComStar and the Com Guard, but ROM considered his loyalty to ComStar was without question and Steiner-Davion tacitly approved of Yekel's stance as "loyal opposition".
