If people stick together, they stay with each other and support each other. e.g. If we all stick together, we ought to be okay.
Si queremos combatir a (el/la) x tenemos que mantenernos unidos.
The present tense is used to describe sth that is happening right now.
Si queremos combatir a (el/la) x tendremos que mantenernos unidos.
We use the future simple to talk about actions happening in the future.
It's an if-then proposition that talks about a likely situation: if sth happens, then sth else happens.

In the sense of giving mutual support to achieve a goal: "If we're going to defeat the enemy, we have to stick together"
"Para vencer debemos permanecer unidos" (Expressing obligation and duty with regard to oneself and others)
The first variant is a literal translation "In order to defeat your enemy, you must act together with other partners." If you join forces with someone, you stick together in order to achieve a common purpose (as a common front in your battle against the enemy)
"Para vencer debiéramos(imperfect subjunctive)/deberíamos(conditional simple tense)/debíamos(imperfect past) permanecer unidos"(depending on the context)
In this case, however, they should unite their forces in a common struggle against their common enemy.
'Unidos venceremos, divididos fracasaremos' / 'Unidos venceremos divididos caemos' / 'Unidos jamás seremos vencidos' / 'Un grupo dividido no se sostiene"("United we stand, divided we fall") / ¡Existimos porque resistimos! / ¡Juntos podemos vencer!
This is a slogan for resistance.
