Warhammer 40,000 (often referred to as Warhammer 40K or just 40K) is a tabletop miniature wargame produced by Games Workshop. The second edition of the game, released in the early 1990s, featured a number of mechanics and components that have since evolved or been streamlined in subsequent editions. One of these components was the introduction of "Wargear Cards".

Here's a brief overview of wargear cards for Warhammer 40K 2nd edition:

Purpose: Wargear cards were used to represent various pieces of equipment, weapons, and artifacts that could be equipped to characters and squads in the game. This made it easier for players to keep track of what each unit had equipped without having to constantly refer to rulebooks or codices.

Types of Wargear: There were various types of wargear cards representing different kinds of equipment. This could range from simple grenades and bolt pistols to powerful artifacts unique to specific factions.

Use: During the army building phase, players could assign wargear cards to eligible units or characters, spending points from their army list budget. Once assigned, the card would be placed near the unit or model it was equipped to, allowing both players to easily see and remember the additional equipment that the model had.

Art and Flavour Text: Each card often had an illustration of the wargear item and some had a brief bit of flavour text that added to the rich lore of the Warhammer 40K universe. This not only made the cards functional but also enjoyable to collect and peruse.

Physical Characteristics: The cards themselves were similar to standard playing cards, made of a durable card stock and were sized to fit into most card sleeves. Some players chose to sleeve their wargear cards to protect them from wear and tear, especially if they were frequently used in games.

For many longtime players of Warhammer 40K, the second edition and its wargear cards hold a special place in their memories. They were a novel way to manage equipment in the game and added a tangible element to army customization.
