Having seen second-placed Muangthong United held to a 1-1 draw at Samut Songkhram on Saturday, the Thunder Castle had the opportunity to move seven points clear with victory over Army.
But in testing conditions at the Thai Army Sports Stadium, both sides were unable to find the breakthrough despite displaying plenty of effort and had to settle for a share of the spoils.
Bangkok Glass were unable to claim a fourth straight win but are now unbeaten in their last six outings after playing out a 1-1 draw against Bangkok United at the Thai-Japanese Stadium.
Despite the blow of having Piyachart Tamaphan sent off in the 21st minute, the Glass Rabbits edged ahead nine minutes later when Flavien Michelini found the back of the net.
However, the numerical deficit eventually took its toll and the hosts forced the draw five minutes from time when Narupon Putsorn found the equaliser.
Relegation-threatened Pattaya United gave their hopes of avoiding relegation a big boost as they climbed up three places to 13th with a 3-0 win at home to Chainat.
Slovakian defender Marian Juhas handed the Dolphins the lead a minute after the half-hour mark, before Obinna Ajoku doubled their advantage six minutes later.
And 11 minutes from time, Jeera Jarernsuk popped up to make it 3-0 and cap off a fine evening for the hosts.
Over at the M-150 Saraburi Stadium, Osotspa Saraburi played out a 1-1 draw with Police United to leapfrog BEC Tero Sasana into seventh place.
The hosts got off to a dream start when Anthony Moura-Komenan opened the scoring in the third minute and they appeared to be heading for victory for much of the 90 minutes.
But in the fifth minute of injury-time, Pinyo Inpinit struck to force the draw for the Silver Shields.
Sunday's final game between TOT and Suphanburi was postponed due to unplayable conditions at the TOT Stadium Chaeng Watthana.
