Introduction

In the following section, we will show the process of detecting specious cases in this survey based on the respondents’ age, military status,and their claimed serve date.

Serve Date

	Overall (N=1020)
September 2001 or later
No	623 (61.1%)
Yes	397 (38.9%)
August 1990 to August 2001
No	836 (82.0%)
Yes	184 (18.0%)
Currently in Military
No	891 (87.4%)
Yes	129 (12.6%)
May 1975 to July 1990
No	838 (82.2%)
Yes	182 (17.8%)
Prior to August 1964
No	976 (95.7%)
Yes	44 (4.3%)
Vietnam Era
No	823 (80.7%)
Yes	197 (19.3%)

These six groups will be assessed by their serve data timing and their age. Also, we assess younger group (>= 2002) by their military staus.

Born 2002 and later

In these four highlighted cases, their military status was not matched by their age, so we need to exclude those from the dataset.
