Dealing with the Infantry Peril

[RVPERTVS]

Thanks guys!! very fast replies, I love this comunity!

I did know about this tactic, I just wanted to clarify what did rq mean by "no delay" maybe he was talking about something else I ignored.

I have a couple of more questions regarding arty plotting: when shifting arty pieces, specially mortars (or at least that´s what I remember) after firing some there´s one tube in the formation that gets more delay than the others in that formation for the next fire mission, what´s this due to?

other thing is: is there a limit of fire missions when performing the "rolling barrage" tactic? I ask because I remember I can peform it up to certain limit of fires, after which delay turns back again to it´s initial delay number.

Thanks in advance
