How to distinguish between level 1,level 2 and level 3 for humans?Heres a brief explanation:

• Level 1: This is considered the "lowest" level, where a person has not undergone any formal military or physical training. In some cases, it could refer to a person who is completely new to combat or physical activities.
• Level 2: This level typically refers to a person who has undergone some level of training, but not necessarily combat-specific. For example, a person who has completed basic military training or basic physical conditioning would be considered level 2.
• Level 3: This is the "highest" level, typically reserved for those who have undergone extensive training in specific combat or physical skills. This could include advanced military training, combat-specific physical conditioning, or other specialized skills.

It's important to note that these levels can vary depending on the context and specific needs of the situation. In some cases, additional levels may be added to account for even more specialized training or expertise.
