[MENTION=19948]Showbread[/MENTION] Here's a little info I dug up on 261, source linked at the end.
261 and 269 seem like they should be similar but are actually very different types of 2. Both are helpful, dutiful and kindhearted. The 269 is the good samaritan that is very helpful, mellow and passive. They struggle with asserting themselves but work tirelessly for others.
The 261 is the true militant 2 that is very 1ish and strident with a focus on being of service. They can think that they are a 1 at first especially with the social instinct.
2-6-1 – The Obedient
This type ignores their own desires. They are very loyal and act as they feel they should and often for others. They want to serve and they tend to expect others to as well.
For example, A 2 that occasionally deals with anxiety by distracting themselves, and deals with anger by controlling their surroundings, would be a 2-7-8, and would be different to a different two that deals with anxiety with vigilance, distrust of authority, and anger by being self critical, which would be
2-6-1.
