Treatment
7 Rs
The British Army treated Operational Stress Reaction according to the 7 Rs:
Recognition – identify that the individual has an Operational Stress Reaction
Respite – provide a short period of relief from the front line
Rest – allow rest and recovery
Recall – give the individual the chance to recall and discuss the experiences that have led to the reaction
Reassurance – inform them that their reaction is normal and they will recover
Rehabilitation – improve the physical and mental health of the patient until they no longer show symptoms
Return – allow the soldier to return to their unit

BICEPS
Modern front-line combat stress treatment techniques are designed to mimic the historically used PIE techniques with some modification. BICEPS is the current treatment route employed by the U.S. military and stresses differential treatment by the severity of CSR symptoms present in the service member. BICEPS is employed as a means to treat CSR symptoms and return soldiers quickly to combat. The following subsections on the BICEPS program are adapted from the USMC combat stress handbook:

Brevity
Critical Event Debriefing should take 2 to 3 hours. Initial rest and replenishment at medical CSC (Combat Stress Control) facilities should last no more than 3 or 4 days. Those requiring further treatment are moved to the next level of care. Since many require no further treatment, military commanders expect their service members to return to duty rapidly. Immediacy
CSC should be done as soon as possible when operations permit. Intervention is provided as soon as symptoms appear.
Other problems that can contribute to anal itching include pinworms, hemorrhoids, tears of the anal skin near the mucocutaneous junction (fissures), and skin tags (abnormal local growth of anal skin). Aside from diseases relative to the condition, a common view suggests that the initial cause of the itch may have passed, and that the illness is in fact prolonged by what is known as an itch-scratch-itch cycle. It states that scratching the itch encourages the release of inflammatory chemicals, which worsen redness, intensifies itchiness and increases the area covered by dry skin, thereby causing a snowball effect. Some authorities describe “psychogenic pruritus” or "functional itch disorder", where psychological factors may contribute to awareness of itching. Ingestion of pinworm eggs leads to enterobiasis, indicative of severe itching around the anus from migration of gravid females from the bowel. Severe cases of enterobiasis result in hemorrhage and eczema. Diagnosis
Diagnosis is usually done with a careful examination of the anus and the patients history. If the presentation or physical findings are atypical, biopsies can be done.In case of long-lasting symptoms, above all in patients over 50 years of age, a colonoscopy is useful to rule out a colonic polyp or tumor, that can show pruritus ani as first symptom. Treatment
The goal of treatment is asymptomatic, intact, dry, clean perianal skin with reversal of morphological changes. For pruritus ani of unknown cause (idiopathic pruritus ani) treatment typically begins with measures to reduce irritation and trauma to the perianal area. Stool softeners can help prevent constipation.
