their roles is to spot corpses and retrieve them to the medic bay ( they prioritize the retrieval of injured infantrymen due to their freshness NOT to specifically save them ) . they're mostly equipped with LMG's due to their mass they possess along with the sled they bring , when a tenchraid happens they bring supplies to the front but still do their role

The more tails they have means how much they've retrieved , they're 3 segments long but 4 segments are need to transport enemy augmented infantry
