You forgot to add the tag at the end "This week's lies brought to you by House Kurita". Yes, we saw the Kurita crews salvaging your mechs.
The Dogs of War clearly needs a new Press Officer - this one's falsehoods are so transparent that one of their fictional orphans could see through it. Not only has there never been an orphanage within 100 clicks of the battlefield, but the only supplies carried by the mechs in question were ammunition for their weapons. The 1st Argyle Rangers had ample time to scan the wrecks, after all, as the Dogs of War lance was utterly crushed despite their numerical advantage.
It should also be noted that once again the battle in question saw a Dogs mech firing at a downed mechwarrior, who thankfully ejected with only minor injuries. As for the FedSuns unit, the last mech on the field, a heavily damaged blackjack, was chivalrously offered favorable terms for their surrender, but refused without response.
It is possible that this was not fanaticism, but fear. Especially with the discovery of the mutilated body of the ex-Dogs of War comm officer who was recently "dismissed". Clearly, the Dogs learned many lessons from their brutish Kurita masters. It might also explain why their Stalker pilot recklessly overheated their mech, resulting in the ammo explosion that killed him or her.
Towards the just end of transparency, something prized as a central freedom in the Federated Suns, the 1st Argyle Rangers will soon release their own report of the recent action. Interested parties and the accredited press will be given cockpit cam records to clear up any disparities in the record.
