Misc rules questions 2, drones, nade launchers, recoil, stance Options

[Riley37]

If I fire the grenade launcher on my Ares Alpha with a Simple Action, and then fire a long burst with my second Simple Action, that's a lotta firepower in one IP. If I fire the long burst first, and then fire the grenade launcher, does the second action take any recoil penalty?

If I install an Ares Alpha (or HK XM30) on a drone, does it need a Targeting (Automatics) autosoft and a Targeting (Heavy Weapons) autosoft to use both functions of that weapon?

Can drones use smartlinks? The +2 bonus requires a smartgun sensor on the gun, and for metahuman users, a way to display the point-of-aim on the user's field of vision; does one pay the listed costs for Image Link and Smartlink as direct upgrades to the drone? There's a listed cost for buying a Camera with sesory enhancements, but presumably a drone without a Camera already has a built-in visual sensor, just not an image-capturing (picture-taking) function.

Do a smartlink system and an airburst link interact/stack in any way other than the +2 to the to-hit roll yielding more net hits to reduce the scatter roll?

Can a drone such as Doberman or Lynx use a bipod or tripod? Can they be effectively "sitting or kneeling" at will, and does that affect anything else? I imagine them as being inherently more stable than a metahuman, if they rest on 4 brakable wheels rather than 2 feet.

Does a flying drone take any different modifiers for recoil?

Why are MMGs, HMGs and assault cannon usable only on foot, and not mountable on vehicles?

If a metahuman extends a bipod or tripod, fires from sitting/kneeling, then runs and fires from another position, do any penalties apply for having an extended bi/tripod? Does sitting/kneeeling affect one's Reaction roll to evade incoming attacks? (I notice that there is both a "Defender prone" +3 to a melee attacker's dice pool AND a "defender prone" -2 to the defender's dice pool.) In other words, is there anything besides house rules to discourage ALWAYS having an extended tripod and declaring a sitting stance? And is there any advantage to firing from prone? (None in RAW, but oddly enough, many soldiers seem to choose prone stance when firing rifles.)

I'm inclined to house-rule that firing from sitting/kneeling gives +1 recoil compensation, and firing from prone gives +2, even without a bipod/tripod. Or possibly even a direct +1/+2 to the attack roll; good stance helps even when using a weapon with negligible recoil (eg a BB gun). Also a cover bonus when the attacker only has LOS to the prone person's head/shoulders, which usually happens at medium or long range.
