Bennie.

This is coolbert:

From MARCONI through Harry at Sharkhunters we have an anecdotal account of a troop being issued and using stimulants during a combat situation:

"I [MARCONI] recall once using Benzedrine [bennie] during my British Army service. Obviously, it was under orders and the  MO [medical officer] administered the tablets to us prior to leaving the base. This was in Aden circa 1967 but the month is vague - - I believe June. He told us to adhere to the dosage and not to exceed it under any circumstances. The reason was that we were involved in a operation in the hills of which Aden seems to be full. We had to be awake and alert for about three days. We were told to go straight to bed on completion of the job - - but being squaddies [English term for infantry], had a couple of cold beers first."

Stimulants during an anti-partisan military  mission and FOR THE PURPOSE OF KEEPING THE INFANTRYMAN ON HIS TOES AND ALERT!!

But do not exceed the dosage under any circumstances. A little bit of the stimulant is good for you, a lot is bad for you.

Drinking alcohol after the mission also not a good idea. Mixing chemicals not under the supervision of a medical profession bad!

Insurrection in Aden during that period threatening British interests, Aden then as now in close proximity to the Bab al-Mandeb maritime choke point.
