Beehive rounds were extensively used in the Vietnam War, for defence of firebase perimeters against massed enemy attacks, and because it could penetrate the thick canopy of the jungle and "pad" it out. The primary beehive round for this purpose was the M546 APERS-T (anti-personnel tracer) shell which projected 8000 flechettes and was direct fired from a near horizontally levelled barrel of a 105mm howitzer. Beehive rounds were also used by recoiless anti-tank weapons including 90mm, 106mm, Ontos's and the M48 tanks.
Subsequently it was reported that the USSR had developed similar rounds for 122mm and 152mm artillery for use in indirect fire, a practice forbidden by US regulations in Vietnam.
Recently, the use of the 105mm M494E3 APERS-T round beehive round in Gaza and the West Bank by the IDF has been criticized.
Recent developments of tank anti-personnel rounds have trended away from the use of flechettes and towards the use of high density metal balls (tungsten) combined with timed explosives in APAM (Anti-Personnel Anti-Materiel) rounds.
