Weelll, adding a Light Vehicle to an all Infantry formation does make it easier to shoot, as it allows AT weaponry to shoot. Equally aircraft 'love' LV, as it maximises their shooting. Keeping Fire Warriors 'pure' is almost mandated to ensure they survive to be able to shoot other infantry
The pathfinder upgrade adds 2 infantry and 1 vehicle to a mechanised fire warrior cadre or to an infantry only cadre. The Tetra recon ("pathfinder") options are all separate formations and certainly are vulnerable to Imperial Thunderbolts.
For the same cost as upgrading two fire warrior formations you get an extra activation that can spread out, and garrison, and call down coordinated fire and help active the fire warriors anyway if you need the extra firepower. Also the smaller formation is easier to hide.
