Geoffrey Barkas' Collar Stud

Origin
Geoffrey Barkas was an English filmmaker who headed the Middle East Command Camouflage Directorate during World War Two. Its purpose was to disguise Allied operations and resources and create replacements to deceive the enemy into firing onto false targets. Their largest mission was Operation Bertram, meant to mislead the location and time of an upcoming Allied attack. Using stand in tanks and disguising real tanks as trucks, they were able to convince the enemy that an attack would happen farther south and later than what they had actually planned.

Effects
When dropped, it covers the nearby area with a camouflage "shield" that matches the pattern of what the stud was dropped on. The "shield" does not physically protect what is contained within, and so can be easily removed. When moved, even in the slightest, the shield will momentarily waver and then dissipate.
