Saw that earlier.

Captagon is converted to amphetamine once ingested..,

Fenethylline is metabolized by the body to form two drugs, amphetamine (24.5% of oral dose) and theophylline (13.7% of oral dose), both of which are active stimulants. The physiological effects of fenethylline therefore seem to result from a combination of these two compounds,[9][10][11] although how is not entirely clear, and seems to involve a synergistic effect between amphetamine and theophylline produced following metabolism.

Military use of stimulant drugs is nothing new, and this should not be surprising.
