The subject of this thread is the following document:

Royal Canadian Artillery, 2nd Canadian Corps, Counter Battery Policy, Operation "Totalize", Appendix L, Addendum A to RCA, Operation Instruction No. 5, 7 August 1944

I would like to ask you for explanation of several phrases or abbreviations related both to this document and generally to artillery operations.

The problems are the following. What does it mean?:

Hi Gregory;

Some answers:

CB = Counter Battery
CBO = Counter Battery Officer
HAA = Heavy Anti-Aircraft
NIL = nothing/blank, etc.
FMN = formation
SP = support
RPG = rounds per gun

Cheers
