Between Golden Rule (2018) and Eyestorm (2018), Colby's Commandos switched from having one Commando and two Locusts to three Commandos in a span of three days with no explanation.
Golden Rule (5 April 2990):
p. 10, eighth paragraph, states, "...First Lance, with Hauptman's Shadow Hawk, Zeller's and Hernandez's Locusts, and Colby's 6M Wolverine."
p. 18, eighth paragraph, states, "...harried from the rear by De Salva's Commando and Hernandez's and Zeller's much smaller Locusts."
Eyestorm (8 April 2990):
p. 8, fifth paragraph, confirms De Salva in a modified COM-1A Commando.
p. 10, third paragraph, confirms Zeller and Hernandez in First Lance.
p. 17, first paragraph, states, "The unit's three Commandos moved in closer now, all three laying down a steady fire from their Shannon Six-Shooter missile launchers."
p. 20, second paragraph, states that Zeller's Commando was lost.
The remainder of the BattleMech roster, save for Zeller's and Hernandez's, is confirmed throughout Eyestorm. I see no mention of the reason for Zeller and Hernandez switching from Locusts to Commandos, nor were any faced in battle for them to salvage. There is also no prior mention of the unit owning more than one Commando.
MechWarrior Destiny (2020), Dragon's Lair (12 April 2990):
p. 6, second column, first paragraph, states that Zeller was injured and his 'Mech was lost.
p. 6, second column, last paragraph, states, "...Hernandez and De Salva in their Commandos."
There are multiple mentions of Hernandez and De Salva piloting Commandos throughout the story.
