pretty much all codex compliant chapters are flexible / able to fill every role. the codex makes sure of that as the codex states:

1st rule is to keep yourself able to fight but make sure you beat the enemy

the rest is tradition  or custom

other vhapters will also do recon (okay aside from minotaurs, who simply deploy as full chapter anyway)
