Arotech Corporation
632 Broadway, Suite 1200
New York, New York 10012

Dear Sirs:

In connection with the registration under the Securities Act of 1933, as amended
(the "Act"), of an aggregate of 5,947,427 shares of common stock (the "Shares"),
par value $0.01 per share (the "Common Stock"), of Arotech Corporation, a
Delaware corporation, comprised of (i) 349,600 shares of Common Stock that are
issued and outstanding (the "Outstanding Shares"), (ii) 4,347,827 shares of
Common Stock that are issuable upon the conversion of currently outstanding
debentures (the "Debentures"), and (iii) 1,250,000 shares of Common Stock that
are issuable upon exercise of currently outstanding warrants (the "Warrants"),
we have examined such corporate records, certificates and other documents and
such questions of law as we have considered necessary or appropriate for the
purposes of this opinion.

Based upon the foregoing, it is our opinion that (i) the Shares have been duly
and validly authorized, (ii) the Outstanding Shares have been duly and validly
issued and are fully paid and nonassessable and (iii) the Shares issuable upon
conversion of the Debentures and exercise of the Warrants will be, when sold,
paid for and issued as contemplated by the terms of the Debentures and the
Warrants (as the case may be), duly and validly issued and 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,
