Teleport homer

From Lexicanum

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 and which enable them to teleport onto the battlefield with much greater accuracy than simply arriving and scattering. 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.
