To tightly seal the Texas border with Mexico would require
a National Guardsman posted every three feet. Since the
border is 1,255 miles long, 2,208,800 Guardsmen would be
required. To loosely seal the border (i. e., a National
Guardsman posted every 300 feet), 22,088 Guardsmen
would be required. There are currently 23,580 National
Guardsmen in Texas. Go figure.
