Modern warfare demands that troops have good mobility. In terms of combat vehicles, it is required that they be lightweight, have good transportability and maneuverability. Replacing the armor steel plates in combat vehicles with titanium alloy can achieve the goal of reducing vehicle weight, improve the performance of weapon systems, and enhance battlefield survivability and combat capabilities. Due to its low density, high yield-to-strength ratio, corrosion resistance and non-magnetism, titanium alloy is the preferred material for the lightweight and performance improvement of military equipment. The rapid deployment and rapid response of military land-based weapons and equipment, as well as the rapid transportation in special areas, have put forward higher requirements for the lightweight of equipment.
Najuspješnije primjene legure titanijuma u vojnoj opremi uključuju glavni borbeni tenk M1A2, borbeno vozilo M2 Bradley i laganu haubicu od 155 mm M777. Poklopac komandnog poklopca borbenog vozila M2 Bradley kovan je od legure titanijuma, a gornja zaštita je od legure titanijuma. Kutije za reaktivni oklop sa strane koriste titanijumske ploče umjesto čeličnih ploča, čime se smanjuje težina reaktivnog oklopa. U poređenju sa M198, lagani 155 mm M777 koristi veliku količinu legure titanijuma i smanjuje težinu za 3175 kg, uspešno postižući smanjenje težine od 44%. Prošireni oklopni transporter M113 također koristi dodatni oklop od legure titanijuma kako bi poboljšao otpornost na metke oklopa.
