Crate (Tiberian Twilight)

There are only two kinds of crates in Tiberian Twilight, Green Tiberium Cores and Blue Tiberium Cores, both are produced by Refueling Stations or by destroying enemy units.

Pick up a Green Tiberium will instantly promote the unit's Veterancy, and restore some health. Pick up a Blue Tiberium Core will install additional armaments to the unit and/or upgrade its weapons' performances, but only affects Offense Class units. Non-Offense Class units will only gain Veterancy and health when picking up a Blue Core.

Information
In campaigns, crates are pre-scripted on battlefields. In skirmish and multiplayer mode, crates are a kind of "scenario condition" that can be switched on/off before game starts. If switched on, crates randomly appears on battlefield and, if not being picked up, will vanish after a certain time.

To pick up a crate, simply order a ground unit (if it's on water, order a ship or submarine or amphibious vehicle or anything can move on/beneath water) to move to its position, mind many crates have field effects.
