The Warriors missed centre-backs Daniel Bennett and Ivan Lovric, who were both injured, which meant that Niklas Sandberg partnered Razaleigh Khalik instead, with Mohd Noh Rahman and Shaiful Esah on the flanks.
John Wilkinson and Rhysh Roshan Rai ran the engine room, and they were supported by Ahmad Latiff and Taisuke Akiyoshi on the wings. Up front, Uruguayan striker Federico Martinez started with Indra Sahdan.
The Warriors had a clear look at goal after just five minutes when Shaiful Esah's cross from the left almost found Martinez. Two minutes later, the danger came from the right when an Ahmad Latiff cross found Indra, who shot into the side netting.
However, the Warriors went ahead in the 10th minute when an in-swinging Shaiful free-kick from the right was diverted into the net by AIK left-back Nils-Eric Johansson.
AIK, who are here for pre-season training, had a couple of chances but couldn't find the target. However, they found the equaliser in the second half through Kenny Pavey in the 66th minute. AIK were reduced to 10 men with 10 minutes left when Johansson brought down Indra Sahdan, who was through on goal, just outside the box.
However, the ensuing free-kick came to naught.
Warriors coach Richard Bok tried out several combinations in the second half, and also gave goalkeepers Rezal Hassan and Hyrulnizam Juma'at a chance after taking off Shahril Jantan.
Noh Rahman had a run in central defence while Mustaqim Manzur and Park Tae Won put in their shifts down the flanks.
Later on, Ahmad Latiff also had a cameo with Indra upfront, adding to Richard's list of options for next week's AFC Champions League playoff against Indonesia's Sriwijaya.
Said Richard after the game: "It was a good game for us to fine-tune our team for the ACL playoffs. We were missing Daniel and Ivan but the other boys gave a good account of themselves."
His sentiments were echoed by AIK assistant coach Andreas Alm, who said: "They gave us some problems with counter-attacks in the first half. We were better in the second half."
Johansson paid tribute to the Warriors' possession play but Richard believes there are still things to work on.
He said: "There are certain areas we can still work on and fine-tune next week.
“But the team played according to what I wanted, which was to keep the ball, pass the ball and move the ball around. This game gave us a good idea on whether we’ve done that enough before Saturday.”
The match which saw a turnout of 2,352 fans, raised a total of $82,000 for the family of former Singapore international Dollah Kassim, who has been in a coma since collapsing during the Sultan of Selangor's Cup veterans game last year.
