What you recognize I don't own, and this is a quick one shot set in Allison of Cybertron that wasn't in the main story

Allison and the rest of the group that was stuck in the past were getting dinner ready soon after they had told the Lone Ranger and Tonto their true identities and their pasts when suddenly they heard someone coming, but quickly identified their new friends and had dinner with the group. Once that was done the Lone Ranger mentioned that they were scouting for the Army and the group volunteered to help

"I don't know, it's not that I don't trust your fighting skills but we're up against Apache's if they hear you coming..."

"We might surprise you actually"

"How so?"

"That's for the mission actually, we don't want to reveal everything too fast even if we're allies and trust you with our identities"

And so soon enough Tonto and the Lone Ranger discover the surprise that the group had for the two, with a few short hand signals they had a plan in place alongside the already established plan of simply scouting the camp that the Lone Ranger and Tonto had made and they spread out and they were quiet, just as quiet as those two, including killing two guards that almost discovered them. Once the scouting was done the report was given to the Army and then the groups left the fort and went to a private area

"Okay, I know most of you are soldiers and as such can fight, but how can you be so quiet in the woods?, from what I understand of your time the military still practices moving quietly but you're not necessarily military and as such shouldn't be as quiet"

"That would be because of my family Lone Ranger, as you know I was raised by robots, now then they have a whole lot of sensors which allows them to fight and work alongside humans without causing any accidents...except Wheeljack, but he's in his labs most of the time those happen and no human is allowed in those labs when they're closed and locked so those are minimized risks. Anyways my family helped create the EDC and also know that alien enemies can be dangerous, as such they occasionally turn off their enhanced sensors and implement stealth training where we have to sneak around the base without getting caught with normal Cybertronian hearing, which they make to normal human hearing, and when I say normal I mean like those who don't have sensitive hearing, which there are people who are sensitive enough to sound that whispers can be heard and irritate them. If anyone is caught we have to go back to the beginning of the course and other punishments are added each time we're caught in training, the only exception is the rookies still in training, and even then after two months they have to start being just as quiet or deal with the consequences. As a result of the training we are very, very quiet in all circumstances and all locations, even with boots on which are naturally more noisy"

"That would do it then, at least in the movement department, what about the killing department?"

"That's a little more difficult depending on several factors, but we're training to do it as quietly as possible by people who are basically trained assassins"

"What?"

"Special Operations soldiers are primarily trained to gather intel now, but when they were actively at war with each other they were also basically assassins, taught to infiltrate the enemy and kill them as quietly, or as loudly as their orders required of them"

"Understood, so I guess it's time to go our separate ways then"

"Yes, it is indeed time to go our separate ways once more"

And that's what they do knowing however that they would meet again in the future at any given time
