Because we are running the special weapons, the ROI is low for each of the upgrades as they will generally affect only one unit each until we expand the squad size. Pistol & Blade are probably irrelevant at this stage, Shotgun & Railgun are only one unit, the only one that I see could be immediately worthwhile is the Rifle - if we also replace Lewwyn's Shotgun for a while.
I'd say that priority has to be getting the Power going so that we can get more contacts setup further down the line. Then I'd suggest making the decision on Supplies when the next Mission comes in: if it's Easy or Moderate, go with SS2 to get more warm bodies out there; if it's Difficult, we probably need the added quality firepower over quantity.
Note that we will have the option to upgrade the Hunter weapons as well, but I believe not until after releasing the Rulers by running the DLC mission.
