Call of Duty Ghosts Operation Homecoming. At least, that is what this reminds me of. Man, now I really wish you could get an announcer for FPS in a moe voice.
"S-Senpai! Support squad-mate reporting in! Do you notice me?"
"Onee-chan~ it's dangerous to go on the battlefield without some protection! Here! (drops juggernaut recon)"
"It's not like I wanted to give you an ammo crate or anything, it's just... the pilot said we had to ditch cargo or refuel so I thought I would just drop it here. You better appreciate it, baka!"
"Player-kun, battle-hind (me) is in your airspace (ehehe~). Don't worry Player-kun... I will (ahn♡) protect you."
