Mas que HESH se esta usando HEF, por ejemplo en los BMP3 y BMD4, la municion de 100 mm es muy recomendada por su pattern.
Fragmentation and high explosive fragmentation (HEF) missile warheads constitute one of the most widely used and developed types of ammunition. They are intended to defeat virtually all types of targets, excluding underground, underwater, and heavily armored ones.(para estos cometidos se usa el misil ARKAN de guiado laser antibloqueo)
Fragmentation warheads are currently defined as munitions that defeat targets by a high velocity spray of a great number of homogeneous inert lethal elements, propelled by the explosion of a high explosive charge. Lethal elements are represented by splinters of uncontrolled fragmentation, preformed fragments, and prefabricated fragments. Consequently, the term "fragmentation" in the broad sense of the word is surely outdated, and the notion "splinter" can only refer to the products of uncontrolled fragmentation.
High explosive fragmentation warheads differ from fragmentation warheads by their ability to penetrate before explosion into soil or any obstacle as part of the missile or separately. In the strict sense of the word, the term HEF warheads can be applied only to ground attack, antiship and similar missiles.
Sometimes, wishing to stress that an air target can be destroyed by a blast wave and explosion products at near misses, specialists make an error when they apply the term "HEF" to SAM warheads outfitted with proximity fuzes. In this case, it would have been more correct to use the term "blast fragmentation warhead" that corresponds to the English term "high explosive blast fragmentation warhead."
As to target type, we distinguish multipurpose (versatile) HEF warheads (for example, HEF warheads with uncontrolled fragmentation intended for MLRS) and specialized fragmentation warheads intended to defeat specific targets. The latter warheads include antipersonnel warheads intended to inflict damage upon unsheltered and lightly protected personnel (with conventional weight "w" of splinters ranging from 0.1 to 1 g), antivehicle warheads intended to defeat ground and air soft-skinned materiel (w = 1 to 10 g), and antiarmor warheads intended to defeat lightly armored targets featuring a steel equivalent of up to 20 mm and other hard-to-hit targets like battlefield missiles (w = 10 to 100 g).
In terms of fragmentation pattern, the following three types of warheads are distinguished:
= warheads with circular patterns;
= warheads with axial patterns;
= warheads with radially directed patterns.
