Grenades don’t work as well on this tower. Carefully climb the stairs to the first floor. An infantryman will charge down the stairs during this sequence, so have a weapon ready to smash him in the face. Continue climbing and look for a sniper in the room on the right.
The next set of stairs has a SMG soldier firing from cover. Shoot right through his wooden cover to kill him, then toss a grenade into the room.
One last floor to go! Move halfway up the stairs, toss another frag grenade, and wipe out any survivors using your machine gun. Grab the med packs before returning to Pierson on the bottom floor.
