Having stood for hours on one spot under the scorching sun, they were believed to have succumbed to exhaustion.
Reports say there was a bit of confusion as some security and medical personnel rushed to the parade ground with stretchers and whisked the collapsed colleagues to the medical shed on the left side of the State Box where the President, Muhammadu Buhari was seated.
However, no casualties were recorded as they were successfully treated and soon regained consciousness.
