I'm writing a feature for the BBC website looking at the technology around automated tanks, known technically as Unmanned Ground Vehicles (UGVs).

These small tracked vehicles represent a new field of autonomous military vehicle. They can rove ahead of an army performing reconnaissance tasks or travel alongside infantry carrying heavy loads. And of course, they can be armed.

I'm interested in hearing from businesses that are designing and promoting UGVs. What is the enabling technology that means UGVs are appearing today? What roles are envisaged for them and how will they be integrated with regular forces?

I'm also keen to hear opinions from anyone with relevant military experience. How practical are these mini-tanks?

I intend to complete interviews for this story by Monday 04 November.

I'm writing a feature for the BBC website looking at practical anti-drone defence in the wake of the Saudi Arabia oil facility attacks. I'm looking for critical thinking around anti-drone defence for large oil installations, assessing the strengths and weaknesses of the various technologies on offer.

I want to hear how the recent attacks have changed perceptions of the threat. And I'm very keen on getting opinions from the oil industry.

I am talking to the manufacturers of counter-drone technology. But I want this piece to be firmly rooted in the implications of the recent attacks in Saudi Arabia. If such relatively cheap technology can have a profound economic and political impact are we seeing a decisive shift in the way wars are fought?

I need to conduct interviews by close of play on Friday 04 October. Please note I will be traveling and working in Geneva September 30 - October 01.

This story can now be viewed on the BBC website.

The Economist Intelligence Unit is producing a report on the subject of lower-latency business opportunities. In other words, they want people who can talk about how 5G networks and associated technologies are creating new business opportunities and how businesses are preparing and planning for this technology.

I need to talk to a small number of US-based subject experts. These should be senior individuals in corporations with a significant interest in lower-latency technology. My aim is to produce four articles, one long piece discussing the findings of a survey associated with the report plus three case studies looking at aspects of lower-latency business.

I must stress that all interviewees have to be from the US. So no matter how informed a UK or European expert may be, I can't use them for these articles. Sorry.

The report will be editorially independent but sponsored by Sprint. I need to establish a short-list of potential interviewees by Tuesday 27 November.

The Economist Intelligence Unit (EIU) is conducting a critical study* of organisational agility. As part of this study I will be interviewing a handful of academics, corporate executives and consultants in the US and UK.

The idea is to assess the real factors that drive and create agility, looking for the substance behind a phrase that is often used too lightly.

I expect each interview to last no more than 30 minutes and I need to establish a shortlist of potential interviewees by Wednesday 11 July.

*The study will be sponsored by Slack but conducted independently by the EIU
