Garrisons for all

[shri]

So, from what little i understand, the Corps represent actual corps which fought in the war, the detachments are brigade level or divisional level troops.
Garrisons are regiments.

Now,
Ottos need to protect a very long coastline, the Austrians need to Garrison the coast/Italy likewise and Belgrade and if Germany pushed into Russia, then they have to garrison Minsk etc and in case their navy loses a lot of ships, Hamburg etc.

So, why not allow say 5 garrisons each to all major countries, Russia anyway starts with around 5 garrisons, so maybe Russia can get 5 more.

This won't break the game. As garrisons are useless in attack, quite weak in defense and cannot entrench, but they can hold the line for 1 turn till troops are operated. This part is Historical.

They can cause problems when the AI puts them in the front-line, but am not against this in principle.

Maybe the script can be disabled for the AI, AI anyway gets a lot of free units in the highest version.

Garrisons are the 5 strength units, think of Volksturm or Homeguard units of WW2. They have literally 0 attack abilities and any corps can kill them in max 2 shots. They are a deterrent to gain the 1/2 turns necessary to operate units to stop a massive amphibious assault, simply because such assaults were impossible in WW1 era.
