They both have 2 open slots IIRC, however because the scoped garands (2 on the standard paths and 1 on the I&R) have a prioritization conflict with 30cals/zooks/BARs, squads equiped with those weapons tend to juggle weapons. What that means is they tend to drop weapons more frequently.
50 sight range on both I believe, standard weapon range of 35.
Standard paths carry 2 scoped garands and 2 m1 carbines where I&R carry a 1:3 ratio respectivly. m1 carbines are better the closer your squad is to target, and the opposite is true of the scoped garands. It's best to keep them at range regardless as the crit on the scoped garand (40% for instant kill) is what you want to utilize the most.
Scoped weapons carry a 0.1 debuff multiplier on the move, so they're basically trash when chasing.
Pathfinder and I&R differences mentioned above ^ plus I&R have a very good arty strike that drops near instantly.
Just for technicality sake, .30mm is tiny AF and I think you're meaning 50cal MG. 50cal for a helpful tip shoots 12.7mm. Yes if you crew a teamweapon with a squad they retain their vision bonuses. This applies to any squad. So this also applies to OST pioneers recrewing MG42s. Self spotting MGs are nice for you, hell for your opponet. Vet 2 paths gain even further sight bonuses so if you can recrew with vet2+ paths the vision transfers to the MG.
Yes they keep their vision stats even if they equip 1919s(30cals), BARs and zooks. However those weapons have 35 range like all other weapons. Although it's possible zooks have 40 range, I'm unsure. I know PTRS rifles have 40 range which makes me second guess myself.
I'm unsure how a blob of I&Rs work since I almost never use them, however I find it best to mix standard paths with rifles or paratroopers since the standard paths are pretty mediocre without weapon upgrades. With the weapon upgrades they're decent, but I do not upgrade mine usually either so I cannot speak from expereince.
Hope this helped!
