## Recruitment and training

Before joining the battalion, all recruits undergo a standard introductory military training course at the Navy training center. Experienced instructors with combat experience teach them the basic rules of handling weapons, combat tactics, and tactical medicine. Additionally, the future soldiers of the 505th SMB undergo emotional hardening, training in discipline, moral stability, and physical endurance.
Following this, the fighters undergo additional training in the battalion and coordinate with the unit they will serve.
Prospective recruits can join a unit by responding to an existing vacancy, for example, on LobbyX, or by contacting the unit directly to receive a letter of recommendation for priority service in the battalion.

## Traditions

The Marine tradition involves completing a psychological obstacle course to earn the right to wear a navy beret. Ukrainian Marines' training program includes a seven-kilometer obstacle course, which is uniform for all units. During this course, servicemen conquer various obstacles — the psychological aspect of the course is paramount, as it tests will, endurance, stability, and the support of fellow soldiers in challenging situations, determining the right to wear a navy beret.
The 505th battalion has a tradition of awarding sleeve badges in a mysterious setting. These sleeve badges are given to soldiers who have completed enhanced training and combat coordination. The ceremony is conducted with torches, ancient Scandinavian rhythms, and the display of Marine Corps and battalion flags. This event serves as an initiation, welcoming new fighters into a community.

### Symbols

The insignia for ceremonial and casual uniforms consists of a heraldic shield stretched on a field of sea waves and a dark blue field decorated with silver edging.
Along the shield's dividing line is a silver-stylized lightning sword accompanied on both sides by silver tongues of flame.
A sword with a blade in the form of lightning and tongues of flame symbolize speed, energy, power, and the power of retribution.
In the mountain above the shield is a blue-green ribbon with a silver edging and a golden inscription: "WITH FIRE AND SWORD". The sleeve badge is made in the Marine Corps of the Armed Forces of Ukraine colors.

## Awards

On May 23, 2024, by the Decree of the President of Ukraine Volodymyr Zelenskyi, the 505th Separate Marine Battalion of the Armed Forces of Ukraine, was awarded the Battle Flag and the "For Courage and Bravery" medal.
