Th resistance didn't have a determinded set of weapons, mostly becaused they used what ever they could get their hands on, they generally have a mix of mostly british some german and a little bit of americian. FFI (French forces of the interier) were trained by americians specials trained for the mission.
American OSS and British SOE agents familiar with popular british weapons like the sten, helped train the french forces of interieur (more organized french offensive), as well as the parisians of the french resistance. Fast learners, the french took their battle to the streets no official contact just some slam bam and run attacks here in their, lowering the enemy moral, and making them more hesitant. Guns weren't the only weapons the maquis used everyday people took up what they knew, wood axes, kitchen knives and even walking sticks became weapons. The ruthless Vichy helped Germans track down more jewish and communist citizens, so you can say they was a little extra incentive to band together and take back what was rightfully theirs. Brothers, Sisters, husbands and wives, neighbour v. neighbour, everyone with reason to pick up arms didn't there was as much bloodshed in the city as german v. FFI as there was French v. French, weapons the same tools used just months before for hunting game and birds, used for freedom and liberation, the same used for murder and oppression. Weapons of vichy was there hope that one day this will as be over, that you will just wake up and all it was, was a bad bad dream, one word Hope, hope in their hearts, and a rifle in his hand, and a man or woman, is undefeatable, for no task big or small will stop him(or her), or his(her) dream from becoming a reality
Sabotage the Germans!
Weapons of the french
The French favoured plastic explosives to dissrupt german supply lines (see above). also they recieved supply drops of british and americain small arms in supply crates dropped by the canadian B-17. Although most of their weapons came from captured german solider that why when you see the rebels they will most likely be holding a german mauser k98 or a german mp 40(favored by most german foot soliders[and as seen above]). americians came and train the maquis with the british sten. Easilly made, and cheap they could be made by the hundreds, or thousands dropped into ocuppied territory.
