OPSEC for incoming fire? Never heard of that one. Maybe something for the soldiers. On Victory (Slayer) there is typicly daily attacks. Sometimes there can be breaks for days though. Longest I recall is close to two weeks. There is a lot of EOD scheduled blasts and those could be mistaken for an attack but there they put out a list of scheduled demo dates/times so you know. Mortar fire is far more common than rockets (not RPG) and all are fairly inaccurate. Mostly minor building dmage and once in a while somebody is unlucky.
They have really done an excellent job in force protection with all the blast barriers erected, every building has them. Once in a while something larger or more accurate hits; best so far has been a few rockets, one hit the main courtyard in the PX on North Victory! Surprising there were only two deaths in that one. I think a soldier who was going home the next day (that really sucks!) and a TCN. The blast barriers really saved some lives in that occasion! There are of course some shooting incidents and car bombs now and then outside or near the ECP's. I just love the tracer lights at night, just like fireworks :)
Worse thing about the mortars is they land in a field out behind my hooch. The rattle and shake the hooch though and disturbs me while i'm trying to sleep after working all night. B@stards! LOL
