Every army has a duty to record the minefields for which it is responsible, even minefields laid during battle. Any mine produced after the Convention [on Certain Conventional Weapons] came into force is required to contain a piece of metal weighing at least eight grams that will aid a mine-detector to identify its presence.

Upon accession to the 1980 Convention on Certain Conventional Weapons, Israel stated:
With respect to Protocol II [to the 1980 Convention on Certain Conventional Weapons], it is the understanding of the Government of Israel that:
(i) Any obligation to record the location of remotely delivered mines pursuant to sub-paragraph 1(a) of article 5 refers to the location of mine fields and not to the location of individual remotely delivered mines;
(ii) the term pre-planned, as used in sub-paragraph 1(a) of article 7, means that the position of the minefield in question should have been determined in advance so that an accurate record of the location of the minefield, when laid, can be made.
