I'm playing Mongoose Traveller 2ed and I'm using the Core Book. Could you explain to me what the Bulky trait means for a weapon? I haven't found any explanation in the book.
On page 75 of my "Traveller_2e_Core_Rulebook.pdf", I have:
Bulky: A Bulky weapon has a powerful recoil or is simply extremely heavy – this makes it difficult to use effectively in combat by someone of a weak physical stature. A Traveller using a Bulky weapon must have STR 9 or higher to use it without penalty. Otherwise, all attack rolls will have a negative DM equal to the difference between their STR DM and +1.
This page also lists a "Very Bulky" trait, which requires STR 12 to use effectively.
