I have often overlooked mission briefing editing mistakes, including grammatical errors that interrupt the flow of reading and mistakes in listings of assets available.
However, I recently read through a mission briefing that takes the cake in terms of editing errors (there are five of them in the short briefing). The mission is R2V One Final Effort, where you fight as the Indian army. Normally, I wouldn't take the time to make a comment about this, but the author of the scenario goes out of his way in the Designer's Notes to thank someone else for "assisting with briefing review and editing". This just doesn't seem right.
In any case, I'm sure the mission is well designed, just needed to chime in on the on-going "mission briefings could use better editing" feedback. Like, seriously.
Here are the five errors:
"...streaming north is what can only be described as..." [should be "in", not "is"]
"...have already been or likely to be liberated..." [should be "are likely" not "likely"]
"Using whatever transport available elements of the..." [should be "available, elements" not "available elements"]
"One Humber IV armoured car is also available to you command to assist" [should be something else (maybe "your command to assist")]
"...estimated that perhaps there are two platoons of worth of infantry." [should be "worth of infantry" not "of worth of infantry"]
