Painted night scene: two servicemen wait in the lit doorway of a field tent while unmarked guards stand by a floodlit fence.

The anthrax booster

Sgt Roderick Castle (Twentynine Palms, March 1997) and Michael Herrera (Padang, October 2009) each say they were given an anthrax 'booster' under guard after the encounter, and each describes an unmarked armed team. Castle's shot came months before the DoD-wide anthrax programme was announced in December 1997.

What if?

If both are right, the same aftermath procedure was used on Marines who saw something they should not have, twelve years apart.

What would settle it

Both men's service medical records, for an anthrax dose outside the normal schedule.
