                SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002


I, D. M. Ervine, Chairman and CEO, President and COO of the company, certify
that:

1.       I have reviewed this quarterly report on Form 10-Q of VSE Corporation
(the "registrant");

2.       Based on my knowledge, this quarterly report does not contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements made, in light of the circumstances under which such
statements were made, not misleading with respect to the period covered by this
quarterly report;

3.       Based on my knowledge, the financial statements, and other financial
information included in this quarterly report, fairly present in all material
respects the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this quarterly report;

4.       The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant and we have:

         (a)  designed such disclosure controls and procedures to ensure that
              material information relating to the registrant, including its
              consolidated subsidiaries, is made known to us by others within
              those entities, particularly during the period in which this
              quarterly report is being prepared;

         (b)  evaluated the effectiveness of the registrant's disclosure
              controls and procedures as of a date within 90 days prior to the
              filing date of this quarterly report (the "Evaluation Date"); and

         (c)  presented in this quarterly report our conclusions about the
              effectiveness of the disclosure controls and procedures based on
              our evaluation as of the Evaluation Date;

5.       The registrant's other certifying officers and I have disclosed, based
on our most recent evaluation, to the registrant's auditors and the audit
committee of registrant's Board of Directors (or persons performing the
equivalent function):

         (a)  all significant deficiencies in the design or operation of
              internal control over financial reporting which could adversely
              affect the registrant's ability to record, process, summarize and
              report financial data and have identified for the registrant's
              auditors any material weaknesses in internal control over
              financial reporting; and

         (b)  any fraud, whether or not material, that involves management or
              other employees who have a significant role in the registrant's
              internal control over financial reporting; and


6.       The registrant's other certifying officers and I have indicated in the
quarterly report whether or not there were significant changes in internal
control over financial reporting or in other factors that could significantly
affect internal control over financial reporting subsequent to the date of our
most recent evaluation, including any corrective actions with regard to
significant deficiencies and material weaknesses.
