General rule was that after firing battery had to displace to a reserve position*. It was up the battery commander to arrange such movement. Each group moved one battery at the time, and in order to enable faster movement number of launchers in battery was reduced to 1/2 (2 for SA-3, 3 for SA-6). This did not really diminish firepower of the battery as both SA-3 and SA-6 can only fire at a single target (with two missiles), so additional launch vehicles are just for a reserve ammo in case of the "Cold war style" mass-attack.
Also, after using search radar it was SOP to displace if anything was in the airspace. Search radars were only used for up the 20 seconds, as it was found out that ARMs can not really get good enough fix on it in that timeframe.
It was found out that old P-12 search radars are fully immune to ARMs due the frequency it operated on. OTOH, it was easy to jam.
Firing positions were arranged as widely dispersed as possible, in order to prevent multiple loses from a same hit. Masking nets (including anti-IR ones) were widely used, and were quite effective. Positions were additionally hidden by the vegetation if possible, and "armored" by emplacements made from tree trunks, which showed to be quite effective vs fragments from the near misses.
False targets were used, including written off radars from SA-2 (which were retired in 1997). "ARM catchers" were used, both reflector and active types.
*Reserve positions were pre arranged by the engineer units, and I am guessing this is the most problematic part for Syrians, as engineer units are desperately needed elsewhere.
