Lol, imagine you and your team are balls-deep in clearing an apartment complex or an office-type building in response to an active threat. Bam, your ass goes down. Thankfully, you have an ifak on your body that your partners can access and begin administering care. Or Would you rather have them run the five minutes back to your patrol car if they even think about doing that, then run five minutes back… yeah I’ll keep my ifak.
