Marine 0311 - Rite in the Rain Tactical Field Book Kit - 4x7 Notebook, Pen, Cover

Used this in the marine corps. The book and cover fit into a cargo pocket. Put pens and an armourers tool in slots. Put call fore fire 9 line and other radio reference cards in the pockets. Biggest regret was not getting one sooner. Does not require the special pen. I’ve never used one but they are sapped to be more rain proof.
