Arotech Corporation
354 Industry Drive
Auburn, Alabama 36832

Dear Sirs:

We have acted as counsel to Arotech Corporation, a Delaware corporation (the
"Company"), in connection with the registration for resale under the Securities
Act of 1933, as amended (the "Act"), of 8,264,463 shares of common stock (the
"Shares"), par value $0.01 per share (the "Common Stock").

As such counsel, we have reviewed the corporate proceedings taken by the Company
with respect to the authorization of the issuance of the Shares. We have also
examined and relied upon originals or copies of such corporate records,
documents, agreements or other instruments of the Company as we have deemed
necessary to review. As to all matters of fact (including factual conclusions
and characterizations and descriptions of purpose, intention or other state of
mind), we have entirely relied upon certifications of officers of the Company,
and have assumed, without independent inquiry, the accuracy of those
certifications.

We have assumed the genuineness of all signatures, the conformity to the
originals of all documents reviewed by us as copies, the authenticity and
completeness of all original documents reviewed by us in original or copy form
and the legal competence of each individual executing a document. We have also
assumed that the registration requirements of the Act and all applicable
requirements of state laws regulating the sale of securities will have been duly
satisfied.

Based upon the foregoing, it is our opinion that the Shares have been duly and
validly issued and are fully paid and nonassessable.

This opinion is limited to the provisions of the Delaware General Corporation
Law.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to this firm under the heading
"Legal Matters" in the Prospectus. In giving such consent, we do not thereby
admit that we are in the category of persons whose consent is required under
Section 7 of the Act.

Very truly yours,

/s/ Lowenstein Sandler PC
