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

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

          effectiveness of the disclosure controls and procedures based on our
          evaluation as of the Evaluation Date;

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.
