At the start of the first campaign mission in Arma 3, the player can have their character walk around the base before hopping into the helicopter, and one of the scenery props... is THIS◊.

Miller: I thought you guys were rescuing me.

Nate: Jesuschrist man, if you forgot to pack the...
Andy: One time! that happened just once! relax, you'll be dicking around with landmines in no time.
Explaining to the reporter how he disarms the mines.
Nate: Now that I have the toolkit and I located them, I simply crawl towards the mines and disable them.
Kate: Surely it has to be more involved than that.
Nate: Yeah, well. I may have glossed over the part where they can, you know... explode.
After successfully locating enemy positions by talking to the locals:
Splender: Fucking-A! thank god for sgt. Hale and his high school french lessons
In one of the Tactical Ops DLC campaigns, shows the early days of the FIA resistance movement long before the events of the main story. The player Character is not, however, a young Wide-Eyed IdealistNew Meat, but Kael Mavros, a grizzled Old Soldier that deserted from the AAF and has a ton of experience in battle. Funnily enough, he's such an asset to have that most squad leaders want him to join them, culminating in this:
