1. State the current situation.
Currently, you either have defending troops, or deployed troops. the land and infra defensive bonus is extremely negligible in comparison to the other battle modifiers.
2. State the problem with the current situation.
When a nation is attacked, and outnumbered, it has no defense other than to turtle. (if it chooses to fight, it will lose much more than if it doesn't defend at all)
3. State how you suggest to changing it.
Add fortification as a choice for defending nations, in the same place where you deploy troops.
Have 3 settings
1) Defending
2) deployed
3) fortified
troops that are defending may either be deployed, or set to fortified.
troops that are deployed may only be undeployed back to defending.
troops that are fortified may only be undeployed back to defending.
Fortifying/unfortifying uses up your 1 deploy per day.
Having any troops in a fortified position causes a 5pt happiness penalty
having more than 40% troops in a fortified position causes a 10pt happiness penalty
Maximum of 60% troops can be in a fortified position.
you cannot fortify the day after unfortifying. (prevents people switching pre/post update to sneak in a collection and avoid penalties)
Fortified troops get a 1000% increase in battle strength (10x the strength of unfortified)
When attacked, the attacking army first battles and kills defending troops, then battles and kills fortified troops.
4. State why your suggestion is better than the current situation
This gives a decent chance to a defending nation other than turtling. Choosing to do this reduces their effectiveness of fighting an offensive ground battle, as they cannot quickly switch from fortified to deployed. Happiness penalty is added so that nations don't always have their troops fortified.
(note: both tanks and soldiers will be able to be set to fortified. Hven't thought about it, but i'd probably use the same ratio for buying tanks as setting them as fortified, so that you can't avoid happiness penalties by just fortifying tanks. i.e. 10% of your fortified soldiers is max amount of fortified tanks)
