There's something to be said for holding a gun so that you don't look like someone who doesn't need to be holding a gun, like a mage or a technomancer. Chino can have APB's Beretta 201T (loaded with explosive ammo) if he wants something to wave around. It also has 2 clips of regular ammo to go with it.
The team also pinched 3 clips of stick-n-shock shotgun ammo off the poachers. Doc can have this.
The sporting goods store only has ammunition for shotguns and hunting/sporting rifles. (The Remington and the Ruger, despite being listed as sniper rifles, are sporting rifles.) Only regular rounds and flechette rounds are available. This is a family-friendly shop in a glossy town which caters to fancy pants corpers. Minigrenades are sadly absent.
Because the coded message is sent from Sam's commlink, it is ultimately his decision whether to send anything or not. (Unless Doc hacks it and does it for him.) I will leave some time for the rest of Team Blue to register their approval or objections to his current plan of sending nothing. If Poindexter is feeling like Sam can't be persuaded on the subject then we'll move forward.
Per an earlier post, when Sam muses whether he knows how to fly a plan he realizes that he does not. Everyone has Pilot Aircraft 0.
