Oh man, I love these kinds of threads. I always like nitpicking the grammar of in-game text descriptions in mods and make overly long and unnecessary suggestions and corrections to them.
Anyway, the description for the Field Support upgrade (and, except for a few words, the Heavy Support upgrade) say, ". . . Also, adds an additional Bren gun or Grenadier Rifle to upgraded Tommy squads and upgrades Sapper Boys rifles to PIATs."
- Change "Also, [it] adds . . ." to "[It] Also adds . . ." for better parallelism with "[It] Allows the . . ." in the first sentence. Ignore the text inside the brackets, that's only to indicate where the subject of the sentence should be.
- "Grenadier Rifle" sounds rather weird. I think it should be replaced with "Rifle Grenade" since that's the actual name of the Tommy upgrade (in singular form), but I'm not sure if that's correct either, realistically speaking.
- Change "Boys rifles" to "Boys AT rifles" for similar reasons with the "Grenadier Rifle" above.
- Change "Tommy squads" and "Sapper" to the actual name of the RMC units, maybe? Since "Tommy squads" is more of a historical/community nickname, changing it to "Royal Marine Sections". Likewise, "Sapper" should be changed to "Marine Engineer".
