## Coat of arms
### Blazon

* Shield
Gules, four cannons saltirewise base to base Or above an anchor paleways Azure fimbriated Argent; augmented of a canton per bend sinister, paly of fifteen of the field and the fourth, base of the second.
* Crest
On a wreath Or and Gules, a triton torque drawing a bow and arrow aimed bendwise Or, above a sea wave Vert (Transparent Sea Green) in front of a Latin cross couped Azure. Motto VAILLANT ET VEILLANT (Valiant and Vigilant).

### Symbolism

* Shield
The red of the shield signifies Artillery; the blue anchor is taken from the coat of arms of the old Coast Defenses of Narragansett Bay; the four cannons form the Roman numeral ten. Battery D, 10th Coast Artillery claims parentage from Battery C, 2nd Coast Artillery (formerly 14th Company, Coast Artillery Corps and Battery C, 2nd Artillery). As the 14th Company, CAC, this company was in the Coast Defenses of Narragansett Bay from 1907 through 1924. The latter has no coat of arms but the addition of a canton is made to indicate this parentage, but divided since one battery can claim this parentage. Battery C, 2nd Coast Artillery was part of the garrison of Fort McHenry and commanded by Captain Frederic Evans during its bombardment, on 13 September 1814, and this event is taken from the coat of arms of the 2nd Coast Artillery and depicted in the fifteen stripes in the canton.
* Crest
The blue cross indicates the Civil War service of Battery E, 5th Artillery (now Battery E, 10th Coast Artillery). It served in the 3rd Division, 6th Army Corps during this conflict. The triton with bow and arrow symbolizes danger rising from the sea, against which the Coast Artillery in its forts must guard.
