The strumming pattern for this section and pretty much the whole song for that matter is based around the good old DDU UDU. You can deviate from that strumming pattern if you choose to but don’t go too far.
There are also points in the song where you specifically have to move away from the DDU UDU. For example, in the TAB you just saw for the verse, you may have noticed that bar 3 looks different. For bar 3, all you need to do is play 4 downward strums. 1 on each beat of the bar.
The chords for that bar are also worth mentioning. You would play a standard open C major chord for the first 2 beats of the bar and then we use a transitional chord to get us to the following A minor. Like a sort of walk down. To play that chord, simply remove your 3rd finger from the C note on the A string and place your 2nd finger on the B note (just 1 fret down). This split bar happens in all of the verses so keep an eye out for it.
Another thing that you should pay close attention to with the Redemption Song TAB are the repeat marks. For example, the first 4 bars in the verse TAB are repeated 3 times before moving onto the next 4 bars. The last bar of those 4 which is a bar of D major is repeated twice.
