Teleport homer
Teleport Homers are antique pieces of equipment used by Space Marines, Chaos Space Marines and Daemonhunters. They produce a signal which can be locked onto by Terminator Armour suits[1a] and which enable them to teleport onto the battlefield with much greater accuracy than simply arriving and scattering.[1b] This is a useful piece of equipment, however to be effective it needs to be on the battlefield and in the correct position, which could put the bearer in substantial danger.[1b][2]
