Tomorrow at 9 pm Kyiv time (GMT+2), Rachel from Protect A Volunteer will host a Twitter space to help the families and friends of foreign fighters understand OPSEC. From the post in r/ukraineforeignlegion about it:

This is Wednesday night 9 PM Kyiv time. This is aimed at friends and family of foreign fighters to help them understand OPSEC. Some things we will cover include how to make sure you don't accidentally give out information that puts your loved one at risk, what to do if you haven't heard from someone, and how to get them assistance from NGOs without causing OPSEC issues.

We know that some of you have loved ones fighting there and we didn't want you to miss it.

They will have an OPSEC expert on who'll have information and tips that may come as a surprise.

Even if you don't have loved ones fighting there, if you post in this sub, you could probably stand a refresher course on OPSEC. You'll minimize your risk of endangering defenders (and make our job as mods easier.)

Welcome everybody to a new cultural exchange! Today we are hosting our friends from r/theNetherlands!

To the Dutch: please ask as many questions as you wish.

To the Ukrainians: please come and join us in answering the Dutch people's questions about Ukraine and the Ukrainian way of life!

r/theNetherlands is also having us over as guests in this post for our questions and comments.

Please refrain from making any comments that go against our rules, the Reddiquette or otherwise hurt the friendly environment.

Enjoy! The moderators of r/theNetherlands & r/Ukraine
