DA Form 5182-R Soil Suction, Water Content and Specific Volume (Lra)

DA Form 5182-R - also known as the "Soil Suction, Water Content And Specific Volume (lra)" - is a United States Military form issued by the Department of the Army.

The form - often mistakenly referred to as the DD form 5182-R - was last revised on March 1, 1983. Download an up-to-date fillable PDF version of the DA 5182-R down below or look it up on the Army Publishing Directorate website.
