The dead Kull warrior that Teal'c and Bra'tac bring back to Stargate Command changes throughout the episode. At first (when alive) it has a plain back body suit on, underneath the armour, but it changes to a patterned one and back again a few times.
Just before the ambush, the rounds feeding into Teal'c's SAW have crimped tips indicating they are blanks. After the fire fight, the rounds have copper jacketed bullets indicating a live round.
Carter tells Hammond the warrior was on the verge of pulmonary failure. Hammond asks "It had a heart attack?" Carter agrees. Pulmonary refers the the lungs, not to the heart.
