Thanks flymaker. Unfortunately that one just randomly assigns different weapons all the time without any control over them. I was hoping to specify or control which weapons replace the original Arma3 ones.
For example, MX always gets replaced with an M4, MX w/ grenade launcher always gets replaced with an M4 w/ M203, MXM always gets replaced with a Mk12 SPR 9or M16A4 w/ ACOG), MXSW always gets replaced with a M249 SAW, etc.
