The base idea for this skin was the male grapple Pilot from Titanfall 2, although the helmet was inspired by that of an IMC Pilot. Perhaps suggesting the Slayer in this universe is ex-IMC, much like he's also technically ex-UAC. He carries a Data Knife in place of the Doom Blade ("Skullhacker"?) and his grenade launcher was inspired by a Smart Pistol. And on his breastplate, you can clearly see the insignia of the 6-4. I do believe the 6-4 is the most appropriate faction for the Slayer: freelance Pilots, with a unique code of honor, that fight for the Frontier's freedom on their own terms. And Doom 64.
Note: Doomguy's a Scorch main. Doesn't need Titans or even anti-Titan weaponry to defeat Titans, but he just likes mechs.
