Several factors influence the delivery of TCCC and are worth mentioning, as understanding them can help you prepare yourself and your CLS personnel to deliver better care.

In addition to environmental considerations (poor lighting, austere conditions, weather), you will usually be in a tactical environment that dictates your movements and communication options, as well as access to your support personnel and equipment.

If you are not under hostile fire, that risk is always present and requires some of your attention.

Depending on your mission profile, you may anticipate different wound patterns or threats.

In the best-case scenario, you will have had time to train and work with your ASM and CLS personnel, but that is not always the case.

Resupply can be erratic (or nonexistent) and tactical considerations may limit what you can take with you.

Finally, the potential for significant delays in evacuation may lead to prolonged field care issues.
