'''Tactical training rounds''' ('''TTR'''), also known as '''tactical lockup rounds''' ('''TLR''')<ref>''[[Halo: Silent Storm]]'', Chapter 5</ref> and occasionally referred to as '''stun rounds''',<ref>''[[Halo 4: Forward Unto Dawn]]''</ref> are a type of training ammunition used to simulate live fire.<ref name="HCH">''[[Halo: Contact Harvest]]'', pg. 215</ref>

==Description==
The TTR has a plastic polymer shell that helps maintain the actual characteristics of bullet flight. Inside, there is a proximity fuse that dissolves the shell when the round comes within 10 centimeters of a surface. Once dissolved, a blob of red paint splatters onto the target. The paint also hides a powerful anesthetic, capable of knocking a target unconscious for hours depending on the area hit, and immobilizes the nano-fibers woven into training clothing, causing it to harden. The target then loses the ability to move the body part that is hit, simulating a bullet wound to that area. At the end of an exercise, the trainees can be unfrozen with a [[TTR baton|specialized baton]].{{Ref/Reuse|HCH}}

The rounds can be used in most UNSC firearms, including [[MA5 series]] assault rifles, [[M6 series]] sidearms, [[SRS99 series]] sniper rifles, as well as [[XBR55 battle rifle]]s.<ref>''Halo: Contact Harvest'', pg. ??</ref><ref>''Halo 4: Forward Unto Dawn Part I''</ref> There are also TTR grenades<ref>''[[Halo: Evolutions - Essential Tales of the Halo Universe]]'', "[[Dirt]]", pg. 122</ref> and claymores.{{Ref/Reuse|HCH}}

A less advanced version of a tactical training round is used in the [[paint pellet gun]].
