ComponentButtonsController.js

({doGeneric: function (component, event, helper) {

    },

    doForeign: function (component, event, helper) {

    },

    doMilitary: function (component, event, helper) {

    }
});

ApexController AccountTransferCont.apx

public without sharing class AccountTransferCont {
    @AuraEnabled
    public static void Military(String RecordID) {
        Account a = [SELECT Id,RecordTypeId FROM Account WHERE Id = :RecordID];
        RecordType rt = [SELECT Id FROM RecordType WHERE Name = 'Military' AND SobjectType = 'Account' LIMIT 1];
        a.RecordTypeId = rt.Id;
        update a;
    }
}

Answer 1

Just pass record id and record type name into your controller to update the current record:

<!--component-->
..........
<!--you can use the same onclick event handler for each button changing only its value-->
<lightning:button label=" - >  Generic Sales" value="Generic Sales" variant="brand" onclick="{!c.doUpdateRecordType}"/>
..........

<!--controller-->
({
    doUpdateRecordType: function (component, event, helper) {
        // as long as your component implements force:hasRecordId
        const id = component.get('v.recordId);
        // you can keep your record type name as value of value attribute of 
        // lightning:button thus reducing repeteable code
        const recordTypeName = event.getSource().get('v.value');
        const action = component.get('c.updateRecordType');
        action.setParams({ id, recordTypeName });
        // If you want to get and process response
        // action.setCallback(this, (response) => {});
        $A.enqueueAction(action);
    },
});

<!--apexController-->
public without sharing class AccountTransferCont {
    @AuraEnabled
    public static void updateRecordType(String id, String recordTypeName) {
        Account a = [SELECT Id,RecordTypeId FROM Account WHERE Id = :id];
        RecordType rt = [SELECT Id FROM RecordType WHERE Name = :recordTypeName AND 
        SobjectType = 'Account' LIMIT 1];
        a.RecordTypeId = rt.Id;
        update a;
    }
}
