Modification provides new clothing choices (incl. positions from DLCs), also keeping the postapocaliptic voluntary militia feel that faction originally was meant to give.
Outfit and armor changes
Upgrades the outfit variation - now Minutemen can wear their faction outfit as a proper underarmor, and are more likely to wear full outfits (non-underarmor clothes). Speaking of armor pieces, I gave them much higher chance to wear them, also on higher levels they can be seen wearing Combat pieces.
Headwear
Minutemen now keeps to wide brimmed hats (e.g. Fedoras, Cowboy and Militia Hats) 
Misc.
Members also have little chance to attire eyewear (Welding and Road goggles).

Mod is *.ESL flagged since it only touches few positions. Also made in FO4Edit, should be stable in-game.
I'm open to discussion so if you noticed some bugs or want a wider choice, I can provide such things without a problem ;)
