Ladies and Gentlemen:

      We are furnishing this opinion of counsel to Markland Technologies, Inc.,
a Florida corporation (the "Company"), for filing as Exhibit 5.1 to the
Registration Statement on Form SB-2, filed by the Company with the Securities
and Exchange Commission under the Securities Act of 1933 on March 17, 2005 and
amended on April 8, 2005, (the "Registration Statement") relating to the
proposed public offering by security holders of the Company of 16,758,690 shares
of the Company's common stock, $.0001 par value per share (the Shares").

      In arriving at the opinions expressed below, we have examined and relied
on the following documents: (a) the Articles of Incorporation of the Company, as
amended; (b) the Bylaws of the Company; (c) the Registration Statement; and (d)
the records of meetings and consents of the Board of Directors and stockholders
of the Company provided to us by the Company. In addition, we have examined and
relied on the originals or copies certified or otherwise identified to our
satisfaction of all such corporate records of the Company and such other
instruments and other certificates of public officials, officers and
representatives of the Company and such other persons, and we have made such
investigations of law, as we have deemed appropriate as a basis for the opinions
expressed below.

      Based upon the foregoing, and subject to the qualifications set forth
herein, we are of the opinion that when the Registration Statement shall have
become effective, (a) with respect to those Shares that are currently
outstanding, when sold, they will be validly and legally issued, fully paid and
nonassessable, and (b) with respect to those Shares that have not yet been
issued, when such shares are issued and sold, they will be validly and legally
issued, fully paid and nonassessable.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal
Matters" in the prospectus forming part of the Registration Statement.

                                               Very truly yours,

                                               FOLEY HOAG LLP
