The Tactical/Tech-case, or T-case, is basically a container storing random weapons or equipment. During combat, multiple packages would be deployed randomly onto the battlefield (Call of Duty: Care Package). Each T-case is made of paristeel to withstand a certain degree of punishment while waiting to be opened. Usually transported via dropship or Science vessel, some of these cases contain prototype technologies to help small squadrons turn the tide of battle (Halo: Resupply Canister and Support Upgrade).
