(I searched, but did not find anything on "ufopedia equipment").
In almost every area of the game, equipment is broken down into primary, secondary, armor, etc.
In the ufopedia, equipment is just a single alphabetical list, not categorized.
Additionally, while there is a need to easily tell what's a close range, medium range, or long range weapon, there's no breakdown by that either; I'm resorting to taking notes.
(I consider it a sign of a problem if I have to take paper notes on a modern game if the online documentation can't address simple stuff).
The docs seem inconsistent -- on one hand, some entries say that most fighting will take place at close/knife range, while other entries imply that medium/long range weapons are essential. This almost implies to me that I need my "main" combat characters to have two primary weapons, one for distance, and one for close combat.
GAAAAHHH.
(For what it's worth, I generally only use plain pistols and laser pistols in XCom. That's good enough until I'm shooting blaster bombs around corners.)
