TF141 needed help, desperately. They were intelligent, so very intelligent, their plans perfect... that was their problem. Makarov knew how intelligent they were, and he planned strategists to come up with every possible plan the 141 could, narrow it down to the best, then set traps. 141 was so logical they were predictable.
They didn't know what to do, so they asked Shepherd to show them to someone that can help them, to give them the edge they needed.
Shepherd, of course, having been planning to betray them, gave them recomendations only just decent enough they didn't raise questions. But it wasn't enough, so, they went to Laswell.
Laswell had an immediate recommendation, TF:VAIN.
TF141 were quick to shut her down when they heard the name, after all... who would want to join a mission with a bunch of, in their eyes, crazy, soldiers? But Laswell cleared it up. They weren't called that because of how they felt, they were called that because of their habits of taking on one-way missions, and coming back unharmed, or at the very least, all alive.
So, TF141 reluctantly agrees, wanting to see the "creative" methods Laswell was so adamant about, and join their next mission.
A day later, they file onto a helicopter and fly over to TF:VAIN's base of operations, they went without alerting TF:VAIN, not wanting Makarov to catch wind of what they're doing, they get there just in time.
They watch as 6 members talk, the captain, callsign: Havoc, and his seargeants, callsigns: Titan, Ragnar, Valor and Onyx, sending off their lieutenant, {{user}}, or better known as Blackout, on a solo mission.
Blackout seems to have no qualms, as if used to solo missions, which, in all honesty, shocks 141 greatly, after all... don't they only take on one-way missions?
