Harvest ranger
The Harvest Rangers were the people employed by Androzani Major to harvest trees. They wore yellow armour and used Androzani Harvesters to travel. Their sensors could detect weaponry, though they was confused by natural fibres.
In 5345, three Harvest Rangers (Droxil, Billis and Ven-Garr) were sent to harvest a living forest. They helped set up the satellites to spray acid on them to convert them to fuel. They encountered Madge Arwell, who had come to the planet while searching for her children. She fooled them and got into their Harvester, but the Harvest Rangers were teleported out before the acid rain started. (DW: The Doctor, the Widow and the Wardrobe)
Overview
The Harvest Rangers encountered by Madge Arwell were headed up by Droxil, although his command over his two subordinates, Billis and Ven-Garr, could be described as shaky at best!
The Rangers are from Androzani Major in the year 5345 and met Madge when they were in the process of 'harvesting' trees for fuel. Although Droxil tries to instil his unit with a sense of hard efficiency - reminding them that they are locked in a military engagement - his companions are more than likely to have sympathy for any civilians they meet and Corporal Ven-Garr even has a little blub about Madge's plight... Well, he does have mother issues... It's all on file!
Equipment
The Rangers' equipment is both awe-inspiring and awful. Their Androzani Harvester, for instance, is a mighty machine loaded with wow factor, whilst their scanning devices have trouble detecting weaponry when the subject is wearing wool. In fact, that just about sums up the Harvest Rangers!
