HEP High Explosive Plastic, muzzle velocity 2,450 fps.  

In this night-fire picture, the flat trajectory of APDS is very clear.   HEP-T at 2,000 Meters looks very different.

Now we reached the end of Table VIII Tank Gunnery 1976.The last engagement was a house—an 8-by-8-foot panel between 1,500 and 2,000 meters from the firing position.The ammunition is HEP-T—High Explosive Plastic-Tracer, the slowest round that tanks fire.The actual rounds we fired is not the service ammo pictured above but the powder-blue inert rounds.
